On planet Tehar, the acceleration of gravity is the same as that on Earth but there is also a strong downward electric field with the field being uniform close to the planet's surface. A 1.50 kg ball having a charge of 5.38 uC is thrown upward at a speed of 20.7 m/s and it hits the ground after an interval of 3.74 s. What is the potential difference between the starting point and the top point of the trajectory?
