The accelerations of a particle as seen from two frames S1 and S2 have equal magnitude 4 m/s^2.

Dear Student

Acceleration of an external particle in any frame of reference is same in three cases

1) When  the relative acceleration of those frames  is zero,

2) When both the frames are equally accelerated with respected to the particle frame of reference.

3) Both the frames are in rest.

 

If we wnat to consider the relative acceleration of S1,S2  we need to consider the particle frame of reference

so c, d,are wrong

a,b are satisfying  1 and 2  so

a, b are correct
