Q. An electric line of force in the $xy$ plane is given by equaton $x^{2} + y^{2} = 1.$ A particle with unit positive charge, initially at rest at the point $x = 1,\ y = 0$ in the $xy$ plane

A) Not move at all
B) Will move along straight line
C) Will move along the circular line of force
D) Information is insufficient to draw any conclusion
Explanation

(c) Charge will move along the circular line of force because $x^{2} + y^{2} = 1$ is the equation of circle in $xy$-plane
