average problem of electrostatics based on spherical conductors.

A small sphere of radius 'a' is inserted in another sphere of 'b'. When b>a & outer sphere is grounded. Find the electric field and capacitance inside and outside of the sphere. A charge of '+q' is present uniformly on the inner sphere with radius 'a'.

Electrostatic force and gravitational force in equlibrium.

Two identical spheres of mass 0.1 g each carrying identical charges are suspended from the same point by two weightless threads each of length 1.3 m. They position themselves so that their centres are 1.0 m apart. Find the charge on each sphere.

Electric Forces and Electric Fields

1.An electron is released a short distance above Earth's surface. A second electron directly below it exerts an electrostatic force on the first electron just great enough to cancel the gravitational force on it. How far below the first electron is the second? 2.Three charges are arranged as shown in the Figure Find the ma ...continues

Determination of the horizontal component of the Earth's magnetic field

Here's the background of our experiment. Purpose: In this experiment you will use a current-carrying loop to determine the horizontal component of the earths magnetic field for our locality. (Massachusetts, USA) Apparatus: 1. Circular conducting loop 2. Compass 3. Power supply and powersate 4. Ammeter 5. Wires Theo ...continues
