A proton is moving at 105 m/s at a point where the potential is 10 V. Later, it is at a place where the potential is 5 V. What is its speed there, assuming energy is conserved? 105 m/s Its speed will depend on how it got to the new place. Less than 105 m/s More than 105 m/s
PROBLEM (a) Find the speed of the proton at x 0.0500 m if s released from rest at x -2.00 cm in a constant electric field with magnitude 1.50 x 103 N/C, pointing in the positive direction. (b) Find the initial speed of an electron fired from x 2.00 cm given that its speed has fallen by half when it reaches x 0.120 m STRATEGY Apply conservation of energy, solving for the unknown speeds. Part (b) involves two equations: the...
