For the spherical distribution: A conducting spherical shell of inner radius b and outer radius c is concentric with a small metal sphere of radius a< b. The metal sphere has a positive charge Q. The total charge on the conducting spherical shell is -Q. (Assume the potential is zero very far from all charges)
a. Find the electric potential for all values of radial distance r. (I first need to find Electric field using Gauss' Law?)
b. How much energy is stored in this distribution of charge?
The gravitational force exerted on a baseball is 2.23 N down. A pitcher throws the ball horizontally with velocity 14.5 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 169 ms. The ball starts from rest.
Electric charge can accumulate on an airplane in flight. You may have observed needle-shaped metal extensions on the wing tips and tail of an airplane, What is the electric field at the surface of each sphere
During a snowball fight, two snowballs travelling towards each other collide head-on. The first is moving east at a speed of 15.3 m/s and has a mass of 0.450 kg, What is the mass of the second snowball
When you turn on your key to start your car, electrons migrate from the negative battery terminal through the electric network to the starter motor and back to the positive battery terminal.
An antelope moving with constant acceleration covers the distance 77 m between two points in time 7.4 s. Its speed as it passes the second point is 15.5 m/s. What is its speed at first point.
Two sound sources radiating in phase at a frequency of 580Hz interfere such that maxima are heard at angles of 0 and 24 from a line perpendicular to that joining the two sources. Find out the seperation between the two sources. The velocity of sou..
Take the mass of the sun to be m_s = 1.99×1030 {rm kg}, gravitational constant to be G = 6.67×10-11 {rm N} cdot {rm m^2/kg^2}, and an acceleration due to gravity at the earth's surface to be g = 9.810 {rm m/s^2}.
