Figure shows two charged particles on an x axis : `-q = -3.20 xx 10^(-19)C` at `x = -3.00m` and `q = 3.20 xx 10^(-19)C` at = + 3.00 m. What are (a) magnitude and (b) direction (relative to the positive direction of the x axis) of the net electric field produced at point P at y = 4.00 m? (c ) What is the magnitude of the net field if y is doubled ?

Explanation

(a) `1.38 xx 10^(-10)N//C`, (b) `180^(@)`, (c ) `2.77 xx 10^(-11) N//C`
