A charge of 6 pC is uniformly distributed throughout the volume between concentric spherical surfaces having radii of 1.4 cm and 3.4 cm. Let: ke = 8.98755 × 109 N · m2/C2 .
What is the magnitude of the electric field 2 cm from the center of the surfaces? Answer in units of N/C.
What is the total charge on Earth's surface implied. explain the strength and direction of an electric field.
A charged particle with a charge-to-mass ratio of |q|/m = 5.7x 108 C/kg travels on a circular path that isperpendicular to a magnetic field whose magnitude is 0.76 T. How much time does it take for the particle to complete onerevolution? t = ?
