Applications of Dimensional Analysis

If force [F], acceleration [A] and time [T] are chosen as the fundamental physical quantities. Find the dimensions of energy.

Show answer and solution

Answer: (c)

Energy = force $\times$ length.
Length in terms of acceleration and time: $L = AT^2$ .
$[E] = [F][A][T^2]$ .
So the answer is (c).
