Well my plan was to use V = E dOn planet Tehar, the free-fall acceleration is same as that on Earth, but there is also a strong downward electric field that is uniform close to the planet's surface. A 2 kg ball having a charge of 5 uC is thrown upward at a speed of 20.1 m/s. It hits the ground after an interval of 4.1 sec. What is the potential difference between the starting point and the top of the trajectory?
So I need to find E and d and I'll have the problem solved.
I used V2^2 = V1^2 + 2ad
v2 is 0, v1 is 20.1, and i used 9.8 for a.
So d came out to 20.6. But I don't think that's correct because I didnt account for the acceleration due to the electric field? So how do I do that?
To solve for E, I wanted to use F/q but not enough info given. Thought about (KQ)/r^2 but not sure if this scenario can be considered point charges...
