Question

if bob of simple pedulum is negatively charge moving on positively charge then time period increase or decrease?

Answer 1

Answer:

Since Time Period of Simple Pendulum is given by - 2*(pi)* sqrt(L/g).When Bob is given a because charge and allowed to oscillate in electric field of positive plate the negatively charged Bob will be attracted by positively charged plate. Hence the net force in vertically downwards direction in increased. This leads to a new value of `g` Which is obviously increased. With the new increased value of `g` being used in the formula we can conclude that the expression of time period decreases as T is inversely proportional to acceleration due to gravity. Therefore time period will decrease.
