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 5
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
Answer 6
Magnitude field at the centre of circle loop
Question 7
A circular …………….. coil
Answer 7
Magnitude field at the centre of coil having n turn
Question 8
An alpha ……………… path
Answer 8
Magnetic field due to moving charge
Question 9
In bohr model ……………. orbit
Answer 9
Question 10
A helium …………….. circle
Answer 10
As question 8 and 9
Question 11
A long ………….. upward
Answer 11
magnetic field due to straight wire

Answer 24
K E of Proton =2 Me V
Question 25
PQ is a …………….. electron
Answer 25
Magnetic field due to wire of distance of 0.6 m
Question 26
An electron …………….. electron
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
Question 33
A proton ……………….. path
Answer 33

directions can be obtained by Fleming left hand rule
page-number : 341
Question 38
Two parallel ………… cylinder
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
Question 43
Two long ………….. wire A
Answer 43
Question 44
A long …………….. repulsion
Answer 44
Question 45
Two very ……………….. same
Answer 45
The force by two wire will be opposite both the wire will attract the middle wire.
Because current in B is more than A
