In the figure shown acceleration of monkey relative to rope if it exerts a force of 80N on string will be?
1 Answer
Gokulraj
If monkey move up then 5kg block will come down with f2=50N
So for monkey : 10a(mass of monkey *acc)-T=(f/15)*10 ........ eqn-(1)
Then for next block : 2T-100=(f/15)*5
By sub t=80 in eqn 3 which is obtained by eliminating 'f' which is
Eqn: a=(3T-100)/10;

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
