2.- A force of 6N to the east acts on a charge Q, when a charge of 5µC is placed 30cm to the east of Q. Determine the value of the charge Q in microcoulomb. pl

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm). (e

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
