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.`

Work done on block in 1 s as observed from frame `S_(1)` is

A
