Consider Law of Homogeniety of Dimensions. Now, choose the correct option:

T2=4π2r3GMTaking dimensions on both ides, we get[T]2=[L]3M−1L3T−2M=M0L0T2∴LHS=RHS Now, T2=4π2r2Taking dimensions on both sides[T]2=[L]2∴LHS≠RHS Now, T2=4π2r3CTaking dimensions on both sides[T]2=L3M−1L3T2M1L0T−1∴LHS≠RHS Now, T=4π2r3G[T]=L3M−1L3T−2=ML0T2∴LHS≠RHS
