On planet Tehar, the free-fall acceleration is the same as thaton Earth, but there is also a strong downward electric field thatis uniform close to the planet's surface. A 2.14-kg ball having acharge of 5.50 μC is thrown upward at a speed of 20.1 m/s. It hitsthe ground after an interval of 4.10 s. What is the potentialdifference between the starting point and the top point of thetrajectory? (Use 9.8 m/s2 for the acceleration due togravity.)
