An observer `A` and `a` charge `Q` are fixed in a stationary frame `F_(1)`. An observer `B` is fixed in a frame `F_(2)` which is moving with respect to `F_(1)`

A particle of mass M is moving with an acceleration a_(0) measured by an abserver 1 standing in a frame of reference moving with a uniform velocity. Another observer 2 is standing in a frame of reference moving with acceleration a

An observer A is at rest in gournd frame, observer B is moving with constant another observer C is moving with constant velocity of 1m/s.
