Two point charges are brought closer together, increasing the force between them

Question

Two point charges are brought closer together, increasing the force between them by a factor of 25. By what factor was their separation decreased? Two point particles with charges +3 mu C and +5 mu C are held in place by 3-N forces on each charge in appropriate directions. Draw a free-body diagram for each particle. Find the distance between the charges. Two charges +3 mu C and +12 mu C are fixed 1 m apart, with the second one to the right. Find the magnitude and direction of the net force on a -2-nC charge when placed at the following locations: halfway between the two half a meter to the left of the e charge What is the magnitude of the net electric force on the charge located at the lower right-hand comer of the triangle shown here? Point charges q_1 = 50 and q_2 = -25 mu C are placed 1.0 m apart. What is the electric field at a point midway between them? Sketch the electric field lines near a point charge Do the same for a point charge Find the electric field at the location of in given that q_2 - q_2 - q_3 - +2.00 pC, q = - 1.00 nC, and the square is 20.0 cm on a and side.

Explanation / Answer

solving problem 4

force between two charge=F=K*q1*q2/r^2.........(1)

if ther are brought together ,let new distance is r'

force=F'=K*q1*q2/r'^2=25F...........(2)

dividind (1) by (2)

1/25=(r'/r)^2

r'=5r

so 5 times
