Questions
A solid sphere of mass m suspended by an inextensible massless string is given angular disturbance. The solid sphere is negatively charged. If it is allowed to oscillate above a large positively charged metallic plate. Its period
detailed solution
Correct option is D
The time period of oscillation is given by T=2πlgThe effective value of g increases due to increase in attraction between positively charged metallic plate and negatively charged metallic bob. Hence time period decreases.Talk to our academic expert!
