Question

Four charges are located on the corners of a square as shown in the drawing. What is the direction of the net electric field at the point labeled P? toward the upper left corner of the square toward the middle of the right side of the square toward the middle of the bottom side of the square toward the lower right comer of the square If there are more electric field lines entering a Gaussian surface than there are leaving the surface, what can you conclude about the sign of the net charge enclosed by that surface? +Q -Q 0 none of these

Explanation / Answer

due to +2q and q , field will be towrads +q and due to -2q and -q, field will be towards -2q.

so direction of net field will ne downwards.

Ans(c)

11. there are more field lines entering that means there is a negative charge enclosed.

b)
