Identify the correct statement(s). 1. To accelerate the motion of an object, a balanced force is required. 2. Balanced forces do not change the state of rest or of motion of an object. 3. Balanced forces do not produce any acceleration; they can change the shape or size of the body. (a) 1 and 2 (b) 2 and 3 (c) 1 and 3 (d) None of these

balanced forces do not change the state of rest or motion of an object
Answer:
B) 2 and 3 are correct
Explanation:
1. To accelerate the motion of an object, a balanced force is required.
No, this is not true if the force is balanced there is no resultant force. F = m.a . if F becomes zero there will be not acceleration.
2. Balanced forces do not change the state of rest or of motion of an object. Yes, already explained if there is balanced force there will be no acceleration. if there is no acceleration there will be no change in velocity. it velocity does not change the object will retain its state. ie either in motion or rest.
3. Balanced forces do not produce any acceleration; they can change the shape or size of the body.
Yes when there is no resultant force but forces are present in the system these forces are resisted by the internal forces by the body which causes stress in the body or the body is deformed.
