Question

1.Four charges are located on the corners on of a square. The sides of the square have a length of 0.05 m. The upper left corner has a charge of q, the upper right corner has a charge of – q, the lower left corner has a charge of 2q, and the lower right corner has a charge of -2q. If the magnitude of q is 10-7 C, find the magnitude of the force exerted on the charge at the lower left corner of this system.

2.According to figure below, where the point P is located so that the magnitude of the electric field(E)=0 at point P? (k = 9 x 109 Nm2C−2, 1 µC = 10−6 C)

3. Determine the electric flux for a Gaussian surface that contains 100 million electrons.

4. A point charge is held stationary at the origin. A second point charge is moved from the point x = 0.20 m, y = 0 to the point x = 0.3 m, y = 0.35 m. How much work is done by the electric force on ?
