I was just wondering. How come the gravitational field strength of the sun is much larger than the gravitational field strength of the moon at when you calculate both values at Earth's position?
Here's the problem:
A particle with a charge of 4.4nC is in a uniform electric field E directed to the left. It is released from rest and moves to the left. After it has moved 6.00 cm, its kinetic energy is found to be 3E-6 Joules.
a) What work was done by the electric force?
.000003 J
b)...
Problem 16.
Three charges: +8.2uC 4.8 cm to the left of 4uC and a -2.3uC 2.1 cm to the right of the 4uC charge.
What is the electric field strength at a point 2.7cm to the left of the middle charge? In N/C.
Note" Is the answer 1.733218664*10^7 from the 8.99*10^9...
Say I have an electromagnet, (that I know the dimentions, geometry, material characteristics, etc) that I am driving with a current that is oscilating at some frequecy how can I calculate the maximum strength of the magnetic field that it can create at that frequency?
and the equations need...
