An electric line of force in the xy plane is given by equation x2+y2=1. A particle with unit positive charge, initially at rest at the point x=1,y=0 in the xy plane
Not move at all
Will move along straight line
Will move along the circular path.
Information is insufficient to draw any conclusion
Charge will move along the circular line of force because x2+y2=1 is the equation of circle in xy-plane.
