A charge q is placed on an equipotential surface and electric field intensity at that place is E. What is the work done to move the charge by a distance x on the surface?

A charge q is placed on an equipotential surface and electric field intensity at that place is E. What is the work done to move the charge by a distance x on the surface? Correct Answer Zero

As the surface is equipotential, all the points on the surface of the plane have the same potential values. Therefore work done to move the charge by a distance x on that surface is zero. The electric field plays no role here.

On which the potential is the same everywhere 2. The movement of charge over such a surface would require no work 3. The tangential electric field is zero 4. The normal electric field is zero Which of the above statements are correct?
Given is the procedure for construction of flow net. Which of the following options is correct sequence of construction? 1. Sketch one flow line or one equipotential line adjacent to a boundary flow line or a boundary equipotential line. 2. Draw the hydraulic structure, the head water elevation and the soil profiles to a convenient scale. 3. Expand the sketching to more equipotential lines and flow lines, always keeping in mind that roughly square figures should result in the process 4. Establish the boundary conditions.
Three friends A, B and C worked together to complete the work. A takes 4 days more to complete same work done by A and B. Work done by C in 4 days is equal to the work done by A in one day. Work done by B in 3 days is equal to the work done by C in 8 days. Find the time in which work will be completed if all three worked together.
