QUESTION #5 Electric Field and Gauss's Law
Consider two infinitely large plane parallel conducting plates as shown below. The plates are uniformly charged with a surface charge density +sigma and -2sigma. The force experienced by a point charge +q placed at the mid point between two plates will be: {{IMG1}}

QUESTION #7 Electric Field and Gauss's Law
A point charge +q is placed at the origin. A second point charge +9q is placed at (d, 0, 0) in Cartesian coordinate system. The point in between them where the electric field vanishes is:

QUESTION #19 Electric Field and Gauss's Law
A small bob of mass 100mathrm~mg and charge +10mathrm~mu C is connected to an insulating string of length 1mathrm~m. It is brought near to an infinitely long non-conducting sheet of charge density 'sigma' as shown in figure. If string subtends an angle of 45^circ with the sheet at equilibrium the charge density of sheet will be: (Given, epsilon_0 = 8.85times 10^-12fracmathrmFmathrmm and acceleration due to gravity, g = 10mathrm~m/s^2) {{IMG1}}
