### Moving Charge and Magnetism Nootan Solutions ISC Class-12 Physics Chapter-7 Numericals ( Kumar and Mittal Nageen Prakashan )

page-number : 338

Question 1

A long ……….35 A…….  wire

Question 2

A long ……50 A…….. wire

by right hand thumb rule magnetic field will be vertically upward

Question 3

Two …………… field

Since the point P is at right side of both the wire therefore M.F. due to both wire will be down ward perpendicular to plane of paper

and its magnitude will be sum of magnitude of magnetic field of two wire.

page-number : 339

Question 4

An electron ………………  50 cm

Q = I t

N e = I t (Q = n e)

Question 5

Two long ……………… directions

In case of same current in two parallel wire magnetic field at mid point will be equal and opposite. so the net field will be zero

However increase of current flowing in anti parallel direction magnetic field due to both the wire will be added

Question 6

A circular …………. centre

Magnitude field at the centre of circle loop

Question 7

A circular …………….. coil

Magnitude field at the centre of coil having n turn

Question 8

An alpha ……………… path

Magnetic field due to moving charge

Question 9

In bohr model ……………. orbit

Question 10

A helium …………….. circle

As question 8 and 9

Question 11

A long ………….. upward

magnetic field due to straight wire

Question 12

the figure ………….. centre O

Magnetic field due to arc

Showing that perpendicular to plane of paper inwardly

Question 13

A current …………. point O

Magnetic field due to bigger arc

Question 14

Compute …………… wire

Magnetic field due to bigger arc

Question 15

An air …………….. solenoid

Magnetic field due to axis of solenoid

Question 16

A 80 cm …………….. centre

Question 17

The magnitude …………… solenoid

Question 18

A 0.5 m ……………….. solenoid

page-number : 340

Question 19

An electron …………. electron

Question 20

calculate …………… of 10 T

Question 21

An electron ……………. electron

direction will be decided by right hand thumb rule

Question 22

An electron …………….. electron

Question 23

A proton …………….. east.

= 0.625 m

(iii)

………………

Question 24

A 2 MeV proton …………… kg.

K E of Proton =2 Me V

Question 25

PQ is a …………….. electron

Magnetic field due to wire of distance of 0.6 m

Question 26

An electron …………….. electron

Energy acquired by electron = eV

Question 27

A uniform ………………. electron

frequency is independent of velocity

Question 28

An α Particle ………… kg

Question 29

An ………………. electron

Question 30

An …………….. path.

K E = 1/2(mv²)

Question 31

An electron ……………… field

Question 32

The velocity ……………A to B

Since electron is moving clock wise therefore magnetic field is vertically down ward

Question 33

A proton ……………….. path

Question 34

What should ……………. m

directions should be find by Fleming left hand rule

Question 35

A 3.0 cm …………… .wire

Force on current carrying conductor

Question 36

Find …………… field of 0.15 T

Question 37

A current ……………… wire

directions can be obtained by Fleming left hand rule

page-number : 341

Question 38

Two parallel ………… cylinder

directions can be obtained by Fleming left hand rule

Question 39

On a ……………. stationary

Question 40

A current ……………. conductor

Question 41

A 60 cm ………….. wire

for neutralising tension

Force should be upward therefore direction of current will be left to right

Question 42

Calculate ………….. wire A

Since when current in wires is flowing in same direction wire are attracted

Question 43

Two long ………….. wire A

Question 44

A long …………….. repulsion

Question 45

Two very ……………….. same

The force by two wire will be opposite both the wire will attract the middle wire.

Because current in B is more than A

Question 46

Calculate …………. kg

Question 47

A cyclotron ……………kg.
