Answer:
The magnitude of force on P is 2.75 N
The magnitude of force on Q is 7.15 N
Solution:
As per the question:
Mass of the object, M = 11.0 kg
Acceleration of the object when the forces are directed leftwards, a =
Acceleration when the forces are in opposite direction, a' =
Now,
The net force on the object in first case is given by:
(1)
The net force on the object in second case is given by:
(2)
Adding both eqn (1) and (2):
Putting the above value in eqn (1):
