A non-conducting sphere of radius 'a' has a charge uniformly distributed in it. The charge density inside the sphere is p. Your answers to the following questions should be in terms of p. epsilon. and 'a' as required.
Find the total charge in the sphere.
Find an expression for the electric field inside the sphere, a distance V from the center.
Find an expression for the electric field outside the sphere, a distance Y from the center.
A basic telephoto lens also uses a combination of a converging lens and a diverging lens. Consider a particular telephoto lens consisting of a converging lens of focal length 40 mm positioned 25 mm from a diverging lens of focal length -20 mm.
Consider the system shown in the figure. The mass of the bucket and liquid is 1.10 kg, and the mass of the ball is 0.150 kg. Find the reading on the scale after the string breaks
