Force F is given by the equation `F=(X)/("Linear density")`. Then dimesions of X are

Options

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

Explanation

`F = (X)/("Linear density")`
Dimension of `F = [MLT^(-2)]`
Dimension of linear density = `[ML^(-1)]`
`therefore " "` X = (linear density)
`= [MLT^(-2)][ML^(-1)] = [M^(2)L^(0)T^(-2)]`
