A man is standing at a spring platform. Reading of spring balance is $60\, kg$ wt. If man jumps outside platform, then reading of spring balance

A

First increases then decreases to zero

B

Decreases

C

Increases

D

Remains same

(AIIMS-2000)

Solution

(a) For jumping he presses the spring platform, so the reading of spring balance increases first and finally it becomes zero.
