Question

If the units of force, energy and velocity are 100 dyne, 400 erg and 10 cm/s respectively. Find the units of Mass, length and time.​

Answer 1

Answer:

Force =100dyne=M1L1T−2

velocity=10scm

=LT−1

Energy=500erg=M1L2T−2

⇒force energy

=L1

=100500

=5cm

⇒(velocity)2

energy

=M1

=(10)2500

=5gm

⇒T=0.5 sec
