. A spherical Gaussian surface of radius 1.00 m has a small hole of radius 10 cm. A point charge
of 2.00 × 10−9 C is placed at the center of this spherical surface. What is the flux through
this Gaussian surface?

Two equal positive charges q1=q2=2.0C are located at x=0, y=0.30m and x=0, y= - 0.30m, respectively. What are the magnitude and direction of the total electric force that q1 and q2 exert on the third charge Q=4.0C at x=0.40m, y=0?

Two point charges are located on the x axis of a coordinate system q1=1.0nC is at x=+2.0cm, and q2=-3.0nC is at x=+4.0cm. what is the total electric force exerted by q1 and q2 on a charge q3=5.0nC at x =0?

An electron is placed at rest in a uniform electric field of 227N/C, 270.0 degree next to the negatively charged plate. What is the final velocity of the electron if it has a mass of 9.11E-31 kg and accelerates for 0.074m ?

A +7.5-nC point charge is 5.0 cm from a -9.4-μC point charge in your laboratory in
California. How much work would you have to do if you left the +7.5-nC charge in the lab
but took the -9.4-μC charge to New York City?

Discuss energy stored in a capacitance
