Question

An electric line of forces in the x-y plane is given by the equation `x^2+y^2=1`. A particle with unit poistive charge, initially at rest at the point `x=1`, `y=0` in the x-y plane, will move along the circular line of force.
A. not move at all
B. will move along straight line
C. will move along the circular line of force
D. informtion is insufficient to draw any conclusion

Answer 1

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