Question

A large insulated sphere of radius r charged with Q units of electricity is placed in contact with a small insulated uncharged sphere of radius r and in then separated. The charge on smaller sphere will now be

  1. Q open parentheses r plus r to the power of straight prime close parentheses
  2. fraction numerator Q r to the power of straight prime over denominator r to the power of straight prime plus r end fraction
  3. Q open parentheses r minus r to the power of straight prime close parentheses
  4. fraction numerator Q over denominator r to the power of straight prime plus r end fraction

The correct answer is: fraction numerator Q r to the power of straight prime over denominator r to the power of straight prime plus r end fraction
