Problem 45P

Two point charges he on the x axis. A charge of +6.2 μC is at the origin, and a charge of −9.5 μCis at x = 10.0 cm. What is the net electric field at (a) x = −4.0 cm and at (b) x = +4.0 cm?

Step-by-Step Solution:

Solution 45P

Step 1 of 4</p>

(a)

Here we need to calculate the net electric field at a point if a charge  is placed at  and another charge  at .

Given data,

Constant,
