A negatively charged object is placed within a positive electric field. What happens to the object? It will be pushed away from the source of the electric field. The object’s charge doubles, and the charge of the source will be halved. It will be pulled toward the source of the electric field. It will not be affected.

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e
