1. A charge of +2.00 x 10-°C is placed at the origin, and another charge of C is placed at x = 1.5 m. Find the point between these two
charges where a charge of +3.00 x 10°C should be placed so that the
net electric force on it is zero.
+4.00 x 10-9

4. if you were an astronaut on the moon, what would you experience? what would you see from your perspective?

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
