Expert Solution
Step 1
Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and is in the direction of net force. Mass being the proportionality constant.
F=ma
Step 2
(a)
Magnitude of resultant force of
Direction of resultant force :
Use Newton's second law of force:
So acceleration of the object is in the direction of net force, i.e., at an angle of counterclockwise from
