Aproton travels through uniform magnetic and electric fields. the magnetic field is in the negative x direction and has a magnitude of 2.04 mt. at one instant the velocity of the proton is in the positive y direction and has a magnitude of 1930 m/s. at that instant, what is the magnitude of the net force acting on the proton if the electric field is (a) in the positive z direction and has a magnitude of 4.70 v/m, (b) in the negative z direction and has a magnitude of 4.70 v/m, and (c) in the positive x direction and has a magnitude of 4.70 v/m?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
