Answer:F=krv *coefficient of viscocity

Explanation:let F be dirctly proportional to Ra

F be directly proportional to Vb

F be directly proportional to ETA c

or f is directly proportional to K Ra  Vb and ETA c

where k is constant of proportionality

Then substitute the dimensional formula of each quantites

[M1 L1 T-2]=[M0 L1 T]a [M0 L1 T-1]b [M1 L-1 T-1]c

On solving we get A=1 B=1 C=1
