Question

If time (t) energy(E) and momentum(P) taken as base quantities then dimension of mass(m) is..??

Answer 1

Answer:

d ) (P^1 A^1/2 T^–1)

 Explanation :

   We know that ,

               Dimensions of Energy = ML^2T^-2 ------------ (1st)

             MOmentum = MLT-1 or P = MLT-1 where (P is momentum) -------- (a)

             Area = L^2  or A^1/2 = L ---------(b) (where A is area)

Using a,b in 1st , we get

             Dimensions of Energy =  P ^1 A^1/2T^-1
