[M^(1)L^(1)T^(-2)] are the dimensions of

[L^1M^1T^-2] Is the dimensional formula for

[L^2 M^1 T^(-2)] is the dimensional formula for

Two physical quantities are represented by P and Q . The dimensions of their product is [M^(2) L^(-4) T^(-4) I^(-1)] and dimensions of their ratio is [I^(-1)] . Then P and Q respectively are

[M^(1) L^(2) T^(-3) A^(-2)] si the dimensional formula of:

[M^1 L^2 T^(-2)] is dimensional formula of

y=x^(2)r+M^(1)L^(1)T^(-2) is dimensionally correct. If r represent displacement, then write dimension of x^(2)

The expression [M^(1)L^(2)T^(-2)] represents
