Question: A cylindrical shell of radius 7.00 cm and length 240 cm has its charge uniformly distributed on its curved surface. The magnitude of the electric field at a point 19.0 cm radially outward from its axis (measured from the midpoint of the shell) is 36.0 kN/C. Find
(a) the net charge on the shell and
(b) the electric field at a point 4.00 cm from the axis, measured radially outward from the midpoint of the shell.
A spaceship leaves earth and travels to star Acrux, which is located 410 ly from earth ( as measured from Earth). If the spaceship travels at 0.95c, how old an occupant be upon arriving at Acrux if she was 13 years old when the ship departed from E..
Ultrasonic acoustic waves are diffracted by a pair of parallel slits 100mm apart. The zeros in the diffraction pattern are spaced at angular intervals of 8.3 degrees. Calculate the wavelength.
