Electric Surface Planer
Physics Questions?
1.Through what potential difference would na electron need to be accelerated for it to achieve a speed of 1.8% of the speed of light (2.99792 x 10^8 m/s) starting from rest? Answer in units of V.
2. On planer Tehar, the free-fall acceleration is the same as that of Earth, but there is also a strong downward electric field that is uniform close to the planet’s surface. A 329 kg ball having a charge of 4.11uC is thrown upward at a speed of 24.8 m/s, and it hits the ground after an interval of 1.79s. The acceleration of gravity is 9.8 m/s^2. What is the potential difference between the starting point ant the top point of the trajectory? Answer in units of kV.
Please help..Im so confused because I keep getting the worng answers..
I think that’s a very hard question for anyone to answer. I thought about the question for a while, and I still couldn’t answer it. I think another option would be to search similar questions on Yahoo or Google search. If you know anyone else in the subject, try calling them or e-mailing them with the question. I am sorry if I am not helping much, but it’s just a though. I really hope it helps.
