Force applied on both the sides of wooden block in equal magnitude reinforces each other. Therefore do not bring about any change in the state of motion or rest of the object. Such types of forces are known as balanced forces.

Direction: In the following questions, a statement of assertion (A) i...
Assertion: If a balanced force is applied on a wooden block, it will move.
Reason: Unbalanced force changes the state of motion or rest while balanced force does not.
The correct answer is option 'D' - Assertion (A) is false but reason (R) is true.
Explanation:
While the reason given is correct, the assertion is false. Let's understand why:
1. Definition of Balanced Force: A balanced force refers to the situation when two equal and opposite forces act on an object. These forces cancel out each other's effect, resulting in no change in the object's motion. The net force in a balanced force situation is zero.
2. Definition of Unbalanced Force: An unbalanced force refers to the situation when two unequal forces act on an object. These forces do not cancel out each other's effect, resulting in a change in the object's motion. The net force in an unbalanced force situation is not zero.
3. Effect of Balanced Force: When a balanced force is applied to a wooden block, the block will not move. This is because the forces acting on the block are equal in magnitude and opposite in direction, resulting in a net force of zero. The block remains in a state of rest or continues its motion with constant velocity.
4. Effect of Unbalanced Force: If an unbalanced force is applied to the wooden block, it will change its state of motion. The block will either start moving if it was at rest or accelerate in the direction of the applied force if it was already in motion.
Therefore, the statement "If a balanced force is applied on a wooden block, it will move" is incorrect because a balanced force does not cause any change in the state of motion or rest of an object. The reason given, that unbalanced force changes the state of motion or rest while balanced force does not, is true and provides a correct explanation for the assertion.
Hence, the correct answer is option 'D' - Assertion (A) is false but reason (R) is true.
