Properties of Field Lines

Assertion :A ...

Question

Assertion :A positive point charge initially at rest in a uniform electric field starts moving along electric lines of force. (Neglect all other forces except electric forces) Reason: Electric lines of force represent path of charged particle which is released from rest in it.

Solution

The correct option is C Assertion is correct but Reason is incorrect
The electric lines of force gives the direction of electric field at that point. It does not represent the path of the charged particle but the force on the particle along the electric filed. Thus the particle will move along line of forces.

Assertion: A proton and an $α$ - particle are projected with the same kinetic energy at right angle to a uniform magnetic field, then the $α$ - particle will move along a circular path of smaller radius than the proton.

Reason : $B q v = \frac{m v^{2}}{r}$ holds good for the charged particle moving in a circular path in a uniform magnetic field.
