A charge of +2.20 μC is at the origin and a charge of -3.20 μC is on the y axis at y = 40.0 cm. 1) What is the potential at poin
ehidna [41]

Explanation:

Formula to calculate the potential at point "a" is as follows.

      V_{a} = \frac{kq_{1}}{r_{1}} + \frac{kq_{2}}{r_{2}}

                 = \frac{9 \times 10^{9} \times 2.2 \times 10^{-6}}{0.4} + \frac{9 \times 10^{9} \times -3.20 \times 10^{-6}}{\sqrt{(0.4)^{2} + (0.4)^{2}}}

                 = -4590 V

Therefore, we can conclude that the potential at point a, which is on the x axis at x = 40.0 cm is -4590 V.

A student who grew up in a tropical country and is studying in the United States may have no experience with static electricity
zzz [600]

Explanation:

Water in the air (humidity) helps to dissipate static charge that builds up. If the air is very dry, the charge can't dissipate, so it builds up until there is enough to spark.

Tropical countries are typically more humid than the United States, but I guess that depends on where you are in the US.
