Q1. An alpha particle (helium nucleus) is travelling along the positive x-axis at 1,250 m/s when it enters a cylindrical tube of radius 0.500 m centered on x-axis. Inside the tube is a uniform electric field of 4.50 x 10-4 N/C pointing in the negative y-direction. How far does the particle travel before hitting the tube wall? Overlook any gravitational forces.
Q2. A plano-convex lens having a radius of curvature of R1 is placed on a concave glass surface whose radius of curvature is R2. Determine the radius of 100th bright ring, assuming 500-nm light is incident normal to the flat surface of the lens.
Q3. Two charged bodies exert the force of .145N on each other. If they are moved so that they are one fourth as far apart, what force is exerted?
