Point charges and are placed 1.0 m apart. What is the magnitude of the force on a third charge placed midway between and and ?
Two fixed particles, each of charge C, are 24 cm apart. What magnitude force do they exert on a third particle of charge C that is 13 cm from each of them?
Two charges µC and µC are fixed 1.00 m apart, with the µC charge to the right of the µC. The resultant force produced on a nC charge by the fixed charges can be described by taking positive horizontal force magnitude as being to the right and positive vertical force magnitude as being upward.
Find the net force halfway between the two fixed charges.
Find the net force 0.500 m to the left of the µC charge.
Find the net force 0.500 m above the µC charge in a direction perpendicular to the line joining the two fixed charges.
