Question

Forces acting on body are said to be balanced if.

• A. Sum of forces is zero.
• B. Direction of forces is the same.
• C. Magnitude and direction of force is same.
• D. Gravitational force acts on it.

Answer 1

The correct option is A

Sum of forces is zero.

Explanation for correct option

Balanced forces are equal in magnitude and opposite in direction. When forces are balanced, there is no change in motion.

i.e; resultant force is $0$. Hence option A is correct.

Explanation for incorrect option

Option B

By definition of balanced force we know that magnitude of force is equal & direction is opposite. Hence option B is incorrect.

Option C

By definition of balanced force we know that magnitude of force is equal & direction is opposite. Hence option C is incorrect.

Option D

By definition of balanced force we know that magnitude of force is equal & direction is opposite. Hence option D is incorrect.

Hence option A is correct.
