A particle is revolving in a circle of radius R . If the force acting on it is inversely proportional to R , then the time period is proportional to

Options

  1. AR
  2. BR^2
  3. C1 / R
  4. D1 / R^2 .

Correct answer

A. R

Step-by-step solution

Given that the force is inversely proportional to R i.e. F 1 R or F= k R or m R ^2= k R or ^2= k m R^2 ^2 1 R^2 array llrl & & & 1 R & 2 T 1 R & T & R array
