Question

Two point charges are separated by 5.6 cm . The attractive force between them is 24 N . Suppose that the charges attracting each other have equal magnitude. |
Part A Rearrange Coulomb's law and find the magnitude of each charge. |

Answer #1

Two charges, Q1 and Q2, are separated by
6·cm. The repulsive force between them is 25·N. In each case below,
find the force between them if the original
situation is changed as described.
(a) The magnitude of charge Q1 is reduced to
Q1/5. N
(b) The distance between the charges is reduced to
2·cm. N
(c) The magnitude of charge Q2 is increased to
5Q2 and the distance is increased to
30·cm. N

Two point charges, A and B, are separated by a distance of 19.0
cm . The magnitude of the charge on A is twice that of the charge
on B. If each charge exerts a force of magnitude 46.0 N on the
other, find the magnitudes of the charges.

15.3 Two equal point charges are separated by a distance of 23
cm. The magnitude of the force that one charge exerts on the other
is 18 N. What is the charge?
15.4 A 5 μC charge and a 3 μC charge are separated by some
distance. If the magnitude of the force that one charge exerts on
the other is 27 N, what is the distance between the two
charges?

Two point charges, A and B, are separated by a distance of 23.0
cm23.0 cm . The magnitude of the charge on A is twice that of the
charge on B. If each charge exerts a force of magnitude 48.0 N48.0
N on the other, find the magnitudes of the charges.
