Question

The two-dimensional cube in the diagram below has charged objects placed at the corners as shown. An electron that is free to move is placed at the exact centre of the cube. In which direction will the electron move?

• A. It will move toward A
• B. It will move toward B
• C. It will move toward C
• D. It will move toward D

Hint:

In electrostatic problems, the direction of motion of a charged particle is determined by the net force resulting from the attraction or repulsion of nearby charges.

Answer 1

The Correct Option is D

In the given setup, the electron, which is negatively charged, will experience an attractive force toward the positively charged objects. The force on the electron depends on the distribution of the charges. The net force is directed toward the corner where the resultant of the forces from the surrounding charges is greatest. From the diagram, the net force will be directed toward point D. Hence, the correct answer is (d).
