If `q= q_(0)(1- epsilon^((-_)/(RC))]`here q = electron change R = electric resistence ,C = electric capacitance , The dimensional formula for `square`are

Options

A. `[A^(-1)MLT^(-2)]`
B. `[AM^(0)L^(0)T^(-1)]`
C. `[M^(0)L^(0)T]`
D. `[M^(0)L^(0)T^(-2)]`

Answer

c

Explanation

`[RC]` is time constant `= [M^(0)L^(0)T]`
Expoent have no dimensions ,
`:. ("square")/(RC)= [M^(0)L^(0)t^(0)] rArr squre = [M^(0)L^(0)t]`
