A constatnt force of 10 N act on a block as shown in figure intal velocity of the particle is zero. It is observed from three frames of reference `S_(1),S_(2)` and ground. The frame `S_(1)` start from rest and move with constnat acceleration `10m//s.` The frames `S_(1)and S_(2)` and particle start moving simultaneously at `t=0.`

The rate at which work is done by constant force on the particle is always non-negative when observed fom

A

`S_(1)` only

B

`S_(1)` and ground

C

`S_(2)` only

D

`S_(1),S_(2)` and ground
