Explanation:
refer hc verma for clarity in concepts because physics is concepts
The force exerted by friction is 7 N.
Explanation:
Given mass of an object, m = 25 kg
Applied force on an object,
Acceleration of an object, a = 0.2 m/s^2
The relation between applied force when it applies on an object and frictional force is given by
Here, F is net force on an object.
As per Newton`s second law,
F = ma
So,
Substitute the given values, we get
Thus, the force exerted by friction is 7 N.
