Points a, b, and c are at the corners of an equilateral triangle of side 1 m. equal positive charges of 5 c are at a and b. (a) what is the potential at point c?

Solution:

we know that the potential of any point is given by

v= kq/r^2(1)

According to the question we have point charges is applied only two point so we must multiply the above equation by 2.

Then we get

V=2kq/r^2        [since charge is unity].

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
