A block of mass ' m ' attached to one end of the vertical spring produces extension x ^ . If the block is pulled and released, the periodic time of oscillation is

Options

  1. A2 2 x g
  2. B2 x g
  3. C2 x 2 ~g
  4. D2 x 4 ~g

Correct answer

B. 2 x g

Step-by-step solution

(A) mg =- kx k = mg x ²= k m ( 2 T )²= k m 4 ² T² = k m T²= 4 ² m k = 4 ² m x m g T=2 x g
