Tension Force Questions

The push or pull influence experienced by an object is known as force. The action-reaction pair of forces acting at each end of the said elements is known as tension. The force transmitted through a wire, rope, and string when pulled by forces acting on opposite sides is referred to as tension force. Work done by tension is always zero.

The tension force is given by the formula: T = mg + ma.

Important Tension Force Questions with Answers

1. What is the value of gravitational force?

1. 1.8 m/s²
2. 5.8 m/s²
3. 7.8 m/s²
4. 9.8 m/s²

Answer: d) 9.8 m/s²

Explanation: The gravitational force is the universal force of attraction acting between two bodies. The value of gravitational force on the Earth is 9.8 m/s^2.

2. Which among the following shows the tension force formula?

1. T = mg * ma
2. T = mg / ma
3. T = mg + ma
4. T = mg – ma

Answer: c) T = mg + ma

Explanation: The tension force formula is T = mg + ma.

Where,

• m – mass
• A – acceleration in m/s²
• T – tension
• g – gravitational force, 9.8 m/s²

3. List the fundamental forces.

Fundamental forces are:

• Gravitational force
• Electromagnetic force
• Strong nuclear force
• Weak nuclear force

4. Choose YES or NO: Is tension force a fundamental force?

1. YES
2. NO

Answer: b) NO

Explanation: Tension force is not a fundamental force. It is one of the non-fundamental forces.

5. Choose the correct answer: Tension force is a kind of ______

1. Contact force
2. Non-contact force

Answer: a) Contact force

Explanation: Tension force is a kind of contact force. Tension force acts when physical contact between two bodies.

6. Give three applications of tension force.

Tension force is applied in jumping rope, while towing a car, and on the trampoline.

7. What is the unit of tension?

1. Watts
2. Joules
3. Newton
4. Radians

Answer: c) Newton

Explanation: The SI unit of tension is Newton.

8. The work done is given by the equation ______

1. W=FS
2. W=F-S
3. W=F+S
4. W=F/S

Answer: a) W=FS

Explanation: The equation for work done is: W = FS.

Where, F is the force and S is the displacement.

9. In the case of tension, what happens to the work done equation W=FS?

1. W=1
2. W=0
3. W=-1
4. None of the option

Answer: b) W=0

Explanation: W=0 since the work done by tension is zero.

10. State true or false: massless does not experience tension forces.

1. TRUE
2. FALSE

Answer: b) FALSE

Explanation: Massless ropes experience two opposite and equal tension forces.
