Short Answer

A particle moves from A to D in while experiencing force. How much work does the force do if the particle follows path (a) ABD, (b) ACD, and (c) AD? Is this a conservative force? Explain.

If particle followed path ABD then work done = .

If particle followed path ACD then work done = .

If particle followed path AD then work done = .

See the step by step solution

Step by Step Solution

Step 1 : Given information

Force,

Curve followed path,

Step 2 : Explanation : 

The force exerted on a mass item that causes it to alter velocity.

When particle follows the path ABD, the work done is

When particle follows the path ACD, the work done is

When particle follows the path AD, the work done is

Hence, in all the conditions the work done is same. So, the force is a conservative force.
