Explain when work is done by the test charge

Explain when the work is done on the test charge.

Read the statement carefully and write 'Yes' for correct statements and 'No' for wrong statements : Work is done on the test charge when it moves from higher to lower potential point.

Find the work done by the Lorentz force.

Find the work done in moving a test charge. From one charged conductor to another

A positive charge +q is located at a point. What is the work done, if a test charge q_(0) is carried around this charge along a circle of radius r about this point?

What is the work done in moving a test charge over the surface of an isolated charged metal sphere.

Correct the following statement. The work done in moving a test charge between two 'points in an electric field depends on the path chosen.
