A positively charged particle is held at the center of a
spherical shell. The figure gives the magnitude E of the
electric field versus radial distance r. The scale of the
vertical axis is set by Es = 8.0
The electric flux passing through a spherical Gaussian surface
of radius r = 1 m having a charge +q at its center is 175.353
Nm2/C. Now, we replace the spherical Gaussian surface with a
cubical one keeping the charge at its center. If the length of the
cube sides is d = 2 m, then the value of the electric flux passing
through each face of the cube is ? Blank 1. Calculate the answer by
read surrounding text. Nm2/C?
When a charged particle moves in an electric field, the field
performs work on the particle. Thus, the energy of the field
decreases, turning into kinetic energy of the particle.
Does the magnetic field of a permanent magnetic similarly lose
energy and perform work when moving a conductor with a current?
A particle with a charge of -60.0 nC is placed at the center of
a nonconducting spherical shell of inner radius 20.0 cm and outer
radius 36.0 cm. The spherical shell carries charge with a uniform
density of -3.37 µC/m3. A proton moves in a circular
orbit just outside the spherical shell. Calculate the speed of the
proton.
