1.	A physical relation is epsilon=epsilon_(0)epsilon_(r) where epsilon= electric permittivity of a medium epsilon_(0)= electric permittivity of vacuum epsilon_(r)= relative permittivity of medium What are dimensions of relative permittivity?
Answer» `[ML^(2)T^(-2)]` `[M^(0)L^(2)T^(-3)]` `[M^(0)L^(0)T^(0)]` `[M^(0)L^(0)T^(-1)]` Solution :(C) `epsilon=epsilon_(0)epsilon_(r)impliesepsilon_(r)=(epsilon)/(epsilon_(0))` RELATIVE permittivity is the RATIO of `epsilon` and `epsilon_(0)` hence it is dimensionsless . i.e. `[M^(0)L^(0)T^(0)]`
