Find the electric field at a point midway between two charges of + 3.0 x 10^-9 C and + 60 x 10^-9 C separated by a distance of 30 cm.
would we utilize coulums law:
[9 x 10^9 * 3.0 x 10^-9 * 60 x 10^-9] / [30/2]
because the particle is now negatively charged so as a whole it should be charged negatively which i think would be done by an evenly distribution of electrons
Suppose you give a metal sphere a negative charge. The electrons on the sphere will be...
A. located right in the middle of the shere
B. distributed in small bunches over the outside of the shere
C. evenly distributed over the outside of the shere
D. none of these
A proton is brought near a positively charged sphere. As it is brought closer its potential energy...
A. increases
B. decreases
C. remains the same
D. cannot determine
Does it decrease (B) because same forces repel causing a decrease in PE?
