Friends plz help me to find its answer ​

Answer 1

Answer:a

Explanation:

i think it must be a

Answer 2

Answer:

answer is (a)

Explanation:

In a solenoid,

The magnetic field is along the axis of the solenoid and the charge particle projected with velocity v is also along the axis of the solenoid that means v and B are parallel and angle between these vectors is zero.

The magnitude of the force on the charge particle is

F=q(∣v∣×∣B∣)sin0

0

F=0

So, the force is zero.
