A quantity` X` is given by `epsilon_(p) L(delta V)/(delta t)` , where `epsilon_(p)` is the permitivity of free space ,L is a length , `delta V` is a potential difference and ` deltat ` is a time interval . The dimensional formula for `X` is the same as that of

Options

A. `M^(0)L^(0)T^(0)A`
B. `M^(1)L^(0)T^(0)A`
C. `M^(0)L^(1)T^(0)A`
D. None of these

Answer

A

Explanation

`[z]=[varepsilon_(0)][l] ([triangleV])/([trianglet])`
`implies [z]=[M^(-1)L^(-3)T^(4)A^(2)][L]([ML^(2)T^(-3)A^(-1)])/([T])`
`implies [z][M^(0)L^(0)T^(0)A]`
