A frame of reference A is moving rectilinearly and uniformly with a velocity `vec(u)` with respect to an inertial frame B. A body is moving with velocity `vec(v)` and acceleration `vec(a)` in an inertial system.
(A): When we use Newton's second law in frame B we write `Sigma vec(F)_("net")=mvec(a)` Now, when we use the same in frame A we will write exactly same `vec(F)_("net") and vec(a)`
(R): All inertial systems are equally suitable for the description of physical phenomenon.

Options

A. If both A and R are true and R is the correct explanation of A
B. If both A and R are true but R is not correct explanation of A
C. If A is true but R is false
D. If A is false but R is true
