Part A = -2.13 * 10^-5 C Click to use the calculator/solver for this part of the problem
Part B = E = 1.02 * 10^-7

What must the charge (sign and magnitude) of a particle of mass 1.43 g be for it to remain stationary when placed in a downward-directed electric field of magnitude 660 N/C?
What is the magnitude of an electric field in which the electric force on a proton is equal in magnitude to its weight?

Part A = 1.84 m
Part B = 1.55 m

If your speed is 3.00 m/s when you start to slide, what distance will you slide before stopping?
If her mass is 20.0 kg, what distance d does she slide (i.e., how far does she move after the push ends)? Remember that the friction force is acting anytime that she is moving?
