[4] What is the repulsive electrical force between two protons 4.0 X 10-15m apart
from each other in an atomic nucleus?
[7] Two charged spheres are 8.45 cm apart. They are moved, and the force on
each or them is found to have been tripled. How far apart arc they now?
[15] A charge of 4.15 mC is placed at each corner of a square 0.100 m on a side.
Determine tl1e magnitude and direction of the force on each charge[16] two negative and two positive point charges magnitude Q = 4.15 mC, arc
placed on opposite comers of a square as shown in . Determine the magnitude
and direction of the force on each charge.
