A metallic coin is given a positive electric charge. What happens to its mass?
Homework Answers
a metallic coin is given a positive electric charge means some electrons from its surface have been taken out, making it contain more protons than electrons and hence resulting in a net positive charge. since electrons possess mass, hence the mass of the metallic coin will get reduced.

Question 3
what happens when a charged Insulator is placed near an uncharged metallic object? They repel each other. They attract each other. They exert no electrostatic force on each other. The charged Insulator always spontaneously discharges. They may attract or repel each other, depending on whether the charge on the insulator is positive or negative. 3. -11 points Three charges are arranged as shown in the figure below. Find the magnitude and direction of the electrostatic force on the...

Humid air breaks down electrically when its molecules become ionized. This happens in an electric field of magnitude E = 3.0 ✕ 106 N/C. Calculate the magnitude of the electric force (in N) on an ion with a net single positive elementary charge in that field.

Two small metallic spheres, each of mass m = 0.35 g,
are suspended as pendulums by light strings from a common point as
shown in the figure below. The spheres are given the same electric
charge, and it is found that they come to equilibrium when each
string is at an angle of θ = 7.9° with the vertical. If
each string has length L = 25.0 cm, what is the
magnitude of the charge on each sphere?
