A +4 µC point charge is in the xy plane at the point (3.0 m, 0.0m)
while a +10 µC point charge is at the point (0.0 m, 1.0 m).
(a) Express the Coulomb force on the +10 µC point charge due to the +4 µC charge in vector notation.
(b) What is the magnitude of the force. Note: The Coulomb is a very large unit of charge and so microcoulombs or µC are often used in calculations.
A µC is 10^6 C.
