Question 1
1 / -0

Assertion: Cyclotron does not accelerate electron.

Reason: Mass of the electron is very small

A
If both assertion and reason are true and the reason is the correct explanation of the assertion

B
If both assertion and reason are true but reason is not the correct explanation of the assertion

C
If assertion is true but reason is false

D
If the assertion and reason both are false

Solution

Cyclotron is suitable for accelerating heavy particles like protons, α-particles etc, and not for electrons because of low mass. Because electrons acquire very high velocities very near to velocity of light and appreciable variation in their mass, occurs.
Question 2
1 / -0

A one metre long wire is lying at right angles to the magnetic field. A force of 1 kg wt. is acting on it in a magnetic field of 0.98 Tesla. The current flowing in it will be

A
100 A

B
10 A

C
1 A

D
Zero

Solution

F = Bil ⇒ 1 x 9.8 = 0.98 x i x 1

⇒ i = 10 A
