Solution

The correct option is C $C$
As points A and D are far away from the charges $Q$ and $- 4 Q$ so for greatest force we will consider only points B and C.
If we put $q$ at C, the attraction force is greater than at B because q is near the $- 4 Q$ . So net force will be gratest at point C.

Related to the diagram of two charges, +Q and −4Q. At which point would a small positive charge q feel the greatest force?

The correct option is C CAs points A and D are far away from the charges Q and −4Q so for greatest force we will consider only points B and C.If we put q at C, the attraction force is greater than at B because q is near the −4Q. So net force will be gratest at point C.
