Question

A metal sphere is insulated electrically and is given a charge. If 50 electrons are added to the sphere in giving a charge, how many Coulombs are added to the sphere?

A. -8 C
B. +8.0x10^-18C
C. +8 C
D. -8.0x10^-20C
E. +8.0x10^-20C
F. -8.0x10^-18C

Answer 1

The charge added to the sphere is +8.0x10^-18C.

Step-by-step explanation:

To determine the number of Coulombs added to the sphere, we need to use the formula Q = ne, where Q is the charge in Coulombs, n is the number of electrons added, and e is the charge of a single electron (1.6x10^-19C).

Given that 50 electrons are added, the charge added to the sphere would be Q = 50 * (1.6x10^-19C) = 8.0x10^-18C.

Therefore, the correct answer is B. +8.0x10^-18C.
