Apologies, I searched google and found a similar problem: rocket is launched straight up from the Earth's surface at a speed of 1.60×10^4 m/s.
What is its speed when it is very far away from the earth?
One of the helpers suggested conservation of energy, and I applied this to this problem it...
1. The problem statement, all variables given/known data
A particle of charge 6 µC is held fixed while another particle of charge 8 µC is released
from rest at a distance of 1.4 m from the first particle. If the mass of the second particle is
3x10-6 kg, what is its speed when it is very far...
Homework Statement
A spherical cavity of radius 4.50 cm is at the center of a metal sphere of radius 18.0 cm. A point charge Q = 6.40 µC rests at the very center of the cavity, whereas the metal conductor carries no net charge. Determine the electric field at the following points.
(a) 2.0...
