Determine the electrical force of attraction between two balloons that are charged with the opposite type of charge but the same quantity of charge. The charge on the balloons is $6\mathrm{.}0{10}^{-7}C$ and they are separated by a distance of $0\mathrm{.}50m.$

Answer:

A balloon with a charge of $4\mathrm{.}0C$ is held a distance of $0\mathrm{.}70m$ from a second balloon having the same charge. Calculate the magnitude of the repulsive force.

Answer:

An object is placed on a table. A charge of $-1\mathrm{.}00C$ is located $1\mathrm{.}00m$ North of the object while a second charge of $+1\mathrm{.}00C$ is located $1\mathrm{.}00m$ to the East of the object. Determine the magnitude of the electric field in N$/$C at the object's location.
