Question

time period of a body moving around a body radius R with velocity V is

Answer 1

Force depends on mass,velocity and radius

[MLT^-2} = k[M}^a{LT^-1]^b[L]^c

= M^aL^bT^-bL^c

Equating the powers we get,

a=1, b+c=1 and -b=-2 or b=2, therefore c= -1

substituting the values we get

F = mv^2/r
