The dimensional formula of Power is ML2T-3.

If every quantity is doubled then it becomes 2M (2L)2 (2T)-3 that is equal to, 2^3*(ML2T-3)*2^-3 EQUAL TO, ML2T-3. So, the answer is unit of power as well as value will not change.

[E]=[ML^2T^ā2] [Eā²]=[(2M4L^2T^ā2)/4] =2[E] Hence, unit of power will double.
