Question

two charges of magnitudes q and 2q are situated at points (0,0)& (3,0).coordinates are in cm .the net electric field at point (3,4)cm is ?

Answer 1

A uniform electric field, with a magnitude of 4 N/C, points in the positive x direction. When a charge is placed at the origin, the resulting electric field ... electric field at x = +4m? A) 3 N/C. B) 2 N/C. C) 1 N/C. D) 4 N/C. E) 0 N/C. Ans: The charge must be negative. Itsmagnitude is: q = Er2 k. = 4×4.

Answer 2

ans is that I don't know the answer of this ok tryin doubnut
