Question

A force is applied on a 6 gm mass (at rest) for 20 seconds. After no force is exerted on it and after travelling distance of 50 cm in 5 seconds, mass stops. The amount of force in Newton will be

• A. \(5 \times 10^{-5}\) Newton
• B. \(5 \times 10^{-3}\) Newton
• C. \(0.2 \times 10^{-3}\) Newton
• D. \(0.2 \times 10^{-2}\) Newton

Hint:

To calculate force, use the formula \(F = ma\), where \(a\) is the acceleration and \(m\) is the mass.

Answer 1

The Correct Option is C

We use the work-energy principle to solve for the force. First, calculate the acceleration of the object using the distance and time. Then, use \(F = ma\) to find the force.
