A body of mass m is suspended to an ideal spring of force constant k . The expected change in the position of the body due to an additional force F acting vertically downwards is

Options

  1. A3 F 2 k
  2. B2 F k
  3. C5 F 2 k
  4. D4 F k

Correct answer

B. 2 F k

Step-by-step solution

Let the change in position of the body due to additional force is x . So, aligned & F= 1 2 k x & x= 2 F k aligned x= 2 F k
