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.
