Answer is given as 1000.Please explain.

Answer»

Let in new system, dimensions be M', L' and T'

Given : 100 M'L'T'^-2 = 100 MLT ^-2 ..(1)

20 M'L'²T'^-2 = (20)(100 ML²T^-2) ..(2)

Solving (1) and (2), L' = 100L

M'T'^-2 = MT^-2 / 100

10 surface tension (MT^-2) in SI unit = 10³M'T'^-2

^{ANS: 1000}
