Two particles with charges +2q and -q are separated by a distance of 0.25 m. If a third particle with charge -3q be placed at the midpoint between the first two particles, what is the magnitude of the net electric force on the particle?
2. A point charge q sits at the origin and a point charge 4q is located at (r, y, z) (d, d,-d), where d is some arbitrary unit of length. Determine the location (not infinitely far away) at which the electric field vanishes. 3. Three point charges q, 24, and -3q are placed at the corners of an equilateral triangle of side length L as shown in the figure below: 2q 3q a) What is the total force on the...
A certain charge Q is divided into two parts q and Q-q, which are then separated by a certain distance. What must q be in terms of Q to maximise the electrostatic repulsion between the two charges?
Three balls, with charges of +q, -2q, and +3q, are placed at the corners of a square measuring L on each side, as shown in the figure. The value of q is 3.10 x 10-6 C, and L-70.0 cm. Assume this set of three balls is not interacting with anything else in the universe, and assume that gravitational interactions are negligible. -2q 9 +3q (a) What is the magnitude of the net electrostatic force on the ball of charge -2q?...
