Question

If the unit of power is 1 million erg per minute, the unit of force is 1000 dyne and that of time is 1/10 second. What is the unit of length ?​

Answer 1

Answer:

We have units of power as s3kgm2

and units of force as s2kgm

Thus we get the Force2Power=kgs

We have power as 106 ergs per min=6001Nm/s

and force as 1000dynes=10−2N

Thus we get Force2Power=600104s/kg

Taking its reciprocal and multiplying it by unit of time we get

1006×101=10006kg=6g
