The numerical value of 10 J energy in a new system of units in which unit of mass 10 g.unit of length 10 cm and unit of time 10 s isa) 106b) 107c 108d) 10

Answer»

energy has dimension of E = ML²/T² M1 = 1 kgL1 = 1mT1 = 1 sec

And M2 = 10gL2 = 10cmT2 = 10sec

so , the value of energy will be reduced by = M(1000/10) * L(100/10)² *T(1/10)-² = 100*100*100 ML²/T².= 10^6*(ML²/T²)

so, option A.
