11. A balloon with a charge of 4.0 x 10-5 C is held a distance of 0.10 m from a second balloon having the same charge. Calculate the magnitude of the repulsive force. PSYW
PLEASE HELP & EXPLAIN STEPS IF POSSIBLE

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

An object starts from rest at point f and speeds up continuously as it moves around an oval. a. choose a point about 1/8 th of the way around the oval from point f, and label it point g. draw a vector to represent the velocity of the object at point g. b. determine the change in velocity vector   between points f and g.
