Question

On planet tehar, the free fall acceleration is the same as that on earth but there is also a strong downward electric field that is uniform close to the planets surface. A 2.00 kg ball having a charge of 5.00 uc is thrown upward at a speed of 22.8 m/s and it hits the ground after an interval of 4.50 s. What is the potential difference between the starting point and the top point of the trajectory? (kV)

Explanation / Answer

Let the total accleration is a

Time taken to go up=4.0/2=2 sec

a=22/2=11 m/s^2

Maximum height=22^2/(2*11)=22 m
