The following...

Question

The following equation gives a relation between the mass m1, kept on a surface of area A, and the pressure P exerted on this area. P=(m1 + m2)x / A What must be the dimensions of the quantities x and m2?

Open in App

Solution

since m1 and m2 are added ...they should be having same D.F. D.F. of p is ML-1T-2 D.F . of right hand side part is M [x]/L2. equate both u will get [x] as LT-2.
