Question

There are four charges, each with a magnitude of 1.91 μC. Two are positive and two are negative. The charges are fixed to the corners of a 0.266-m square, one to a corner, in such a way that the net force on any charge is directed toward the center of the square. Calculate the magnitude of the net electrostatic force experienced by any charge.

Answer #1

There are four charges, each with a magnitude of 2.18 µC. Two
are positive and two are negative. The charges are fixed to the
corners of a 0.21-m square, one to a corner, in such a way that the
net force on any charge is directed toward the center of the
square. Find the magnitude of the net electrostatic force
experienced by any charge.

A charge of -2.99 μC is fixed at the center of a compass. Two
additional charges are fixed on the circle of the compass (radius =
0.116 m). The charges on the circle are -4.08 μC at the position
due north and +5.18 μC at the position due east. What is the
magnitude of the net electrostatic force acting on the charge at
the center?

A charge of -2.99 μC is fixed at the center of a compass. Two
additional charges are fixed on the circle of the compass (radius =
0.115 m). The charges on the circle are -3.94 μC at the position
due north and +4.96 μC at the position due east. What is the
magnitude of the net electrostatic force acting on the charge at
the center?

A charge of -5.0 μC is fixed at the center of a compass. Two
additional charges are fixed on the circle of the compass, which
has a radius of 0.040 m. The charges on the circle are +2.0 μC at
the position due north and -3.0 μC at the position due east. What
are the magnitude and direction of the net electrostatic force
acting on the charge at the center?

Three charges, each of magnitude 6 nC, are at separate corners
of a square of edge length 4 cm. The two charges at opposite
corners are positive, and the other charge is negative. Find the x
and y components of the force exerted by these charges on a fourth
charge q = +3 nC at the remaining (upper right) corner. (Assume the
+x axis is directed to the right and the +y axis is directed
upward.)

Three equal positive point charges of magnitude Q = 9.00μ C are
located at three corners of a square of edge length d = 8.1 cm. A
negative charge -27.00μ C is placed on the fourth corner. At the
position of the negative charge, what is the magnitude of the
electric field due to the three positive charges?
What is the magnitude of the attractive force on the negative
charge?

Four point charges are located at the corners of a square. Each
charge has magnitude 1.70 nC and the square has sides of length
