Answer to Question #79342 in Electric Circuits for prime nanven

Question

1. The electron and proton atom are separated ( on the average) by a distance of 5.3 × 10-11m. find the magnitude of the electric force and the gravitational force between the two particles.
2. Calculate the potential difference between two points x,y in the field of a single charge of
1.5 × 10-6C if the products and the differences of the distance of x and y from the 15cm and 2cm respectively
3. A charge 4.5 × 10-9C is placed in an electric field of magnitude 9.6 × 10-5 NC-1 upwardly directed. What work is done by the electric force in moving the charge 60cm to the left.

4. A charge 4µC is place 60cm away from a charge of 4µC what is the electric field at point?
a. p midway between the charges
b. at point q 4cm from p and equidistance from the two charges
