Question

Two blocks of mass 10kg and 20kg are connected by a light string as shown in the figure. If two forces of 80N and 20N are exerted on the system the net acceleration of 10kg mass will be

Answer 1

Answer:

Hence,

For 10kg: T=ma

=10×12

=120N............(1)

For 20kg F−T=ma

200−120=20α

80=20a

a=4ms

∴ acc of 20kg=4ms

−2
