4. Reference frame A is moving with a velocity With respect to earth and reference frame B is moving with a velocity V2 with respect to reference frame A. If M, and M, are the masses of a body in A and B respectively and Cis the speed of light, then what is the value of M, IMR -1/2 (a) 1-V/c (b) 2 C (c)1-(-V,}le(d) (1-V1c2) -1/2
