Solution

## The correct option is B 6 gWe have units of power as kgm2s3and units of force as kgms2Thus we get the PowerForce2=skgWe have power as 106 ergs per min=1600Nm/sand force as 1000dynes=10−2NThus we get PowerForce2=104600s/kgTaking its reciprocal and multiplying it by unit of time we get6100×110=61000kg=6g
