The force F acting on a body moving in a circular path depends on mass m of the body, velocity v and radius r of the circular path. Obtain an expression

for the force by dimensional analysis (Take the value of k = 1).


Take f=k*[M]a[V]b[L]c [MLT-2]=k*[M]a[V]b[L]c [MLT-2]=k*[M]a[LT-1]b[L]C EQUATING POWERS, 1=a 1=b+c -2=-b 1=2+c c=-1 therfore f=kmv2/r
