page-number : 338

Question 1

A long ……….35 A…….  wire

Answer 1

Question 2

A long ……50 A…….. wire

Answer 2

by right hand thumb rule magnetic field will be vertically upward

Question 3

Two …………… field

Answer 3

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

Answer 4

Q = I t

N e = I t (Q = n e)

Question 5

Two long ……………… directions

Answer 26

Energy acquired by electron = eV

Question 27

A uniform ………………. electron

Answer 27

frequency is independent of velocity

Question 28

An α Particle ………… kg

Answer 28

Question 29

An ………………. electron

Answer 29

Question 30

An …………….. path.

Answer 30

K E = 1/2(mv²)

Question 31

An electron ……………… field

Answer 31

Question 32

The velocity ……………A to B

Answer 32

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

Answer 38

directions can be obtained by Fleming left hand rule

Question 39

On a ……………. stationary

Answer 39

Question 40

A current ……………. conductor

Answer 40

Question 41

A 60 cm ………….. wire

Answer 41

for neutralising tension

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

Question 42

Calculate ………….. wire A

Answer 42

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