Question

An electric line of force in the $x - y$ plane is given by the equation $x^{2} + y^{2} = 1$ . A particle with unit positive charge, initially at rest at the point $x = 1$ , $y = 0$ in the $x - y$ plane will move along the circular line of force.

Solution

The correct option is B False
The equation of line of force suggest a circular motion in $x - y$ plane, but electric field line can never be a closed loop. Hence the statement is false.
