Electrostatics Question 228

Question: An electric line of force in the xy plane is given by equation $ 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 [IIT 1988]

Options:

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

Show Answer

Answer:

Correct Answer: C

Solution:

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