Q1. A skateboarder shoots off a ramp with a velocity of 7m/s, directed at an angle of 55° above the horizontal. The end of the ramp is 1.40 m above the ground. Let the x axis be parallel to the ground, the +y direction be vertically upward, and take as origin the point on the ground directly below the top of the ramp. (a) How high above the ground is the highest point that the skateboarder reaches? (b) When the skateboarder reaches the highest point, how far is this point horizontally from the end of the ramp?

Q2. A spherical conducting shell has an interior radius of 18 cm and an outer radius of 21cm. The shell carries a net charge of -2.4 micro coulombs. A point charge of charge +6.4 micro coulombs is placed at the center of spherical shell.

i. calculate the amount of charge on the INSIDE of conducting shell.

ii. Use Gauss's law to find the electric field 12.0 cm from the center of system.
