Chapter 12, Problem 3SP
Suppose that one of the two charges in synthesis problem 2 is twice as large as the other one. Use the procedures suggested in parts a and b of synthesis problem 2 for this new situation. (When sketching the field, there should now be twice as many field lines emerging from the larger charge as from the smaller charge.)

An object of mass 5 × 10-6 g is placed over a thin positively charged sheet of surface density of charge σ = 4.0 × 10-6C/m2 (figure shown below). Estimate the charge that should be given to this object so that upon release it will not fall down. Calculate the number of electrons that is to be removed to give this charge. How much mass loss is caused by this removal of electrons?
Two point charges of mass m each are suspended in the gravitational field of the Earth by two non-conducting massless strings, each of length 1,
attached to the same fixed point. The spheres are given equal charges of the same sign. As a result each string makes angle a to the vertical (see
figure below). Write down an expression for the tension of a string Tin terms of Coulomb force Fc between the charges and the angle a.
Use the following notation (without the quotes): "/" for division, "*" for multiplication, "+" an "-" as usual. For powers used "^2", while for square root
use "sqrt". To indicate that square root applies to the whole expression use brackets - for example, for √AB use sqrt(A*B). For Greek letters such as ,
a etc. use pi, alpha. For example to get √AB use 1/pi*A^2/B*sqrt(AB). Please use the exact variables given in the conditions of the problem: e.g
