Question

convert a work of 25 g cm into the units of M.K.S system using method of dimensional analysis. ​

Answer 1

Answer:

Hope you like the answer.

Explanation:

As we know the formula,

N2= N1 [ g/kg]^a [ cm/m]^b [ s/s]^c

Dimensional unit = ML²T-² so, here a= 1, b=2, c=-2 hence put these values in above formula and n1= 25g

now, N2= N1 [ g/kg]¹ [ cm/m]² [ s/s]-²

N2= 25[10-³kg/kg]¹ [ 10-²]² [60s/60s]-² [ here s/s cancel]

N2= 25× 10-³×10-⁴

N2= 25× 10-⁷ Ans
