What is the magnitude of the centripetal force that must be applied in order for a
0.5 kg ball on a 2.0 m string to spin with
uniform circular motion at 5.0 m/s?

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

b) phosphorus pentoxide

c. magnitude and direction

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
