The electric field at a point in space is E= (400i +100j) N/C
1) Obtain the magnitude of the proton acceleration?
2) Obtain the magnitude of the electron acceleration?
In an experiment designed to measurethe speed of light, a laser is aimed at a mirror that is 47.0 kmdue north. A detector is placed 120 m due east of the laser. Themirror is to be aligned so that light from the laser refelects intothe detector.
A small can is hanging from the ceiling. A rifle is aimed directly at the can, as the figure illustrates. At the instant the gun is fired, the can is released. Ignore air resistance and show that the bullet will always strike the can, regardless of t..
First work out the momentum before and after hitting the table. Don't forget the gravitational force.
the electric potential v in the space between two flat parallel plates is given by v 1200x2 where v is in volts if x
