To check the correctness of any equation, we can use the method of dimensional analysis. So, here, on left side of the equation the given quantity is Force. Which is having dimensions,
[F] = [MLT−2]
The dimensions of the right hand side should also be same.
So,
[6πηrV] = [ML−1T−1][M0LT0][M0LT−1] = [MLT−2] = [F]⇒ [LHS] = [RHS]
Hence the given equation is correct.
Hope this information will clear your doubts about the topic.
