Q1. How many extra electrons reside on pith balls? Know that the charge of the electron is
1.602 x 10-19 C.
Value of charge between both pith balls =6.618*10^-9
Mass per pith ball =0.05g
The angle θ between the string and the vertical line (measured by the protractor): 6°
The separation distance r between the centers of the pith balls: 8.2 cm
Homework Answers
the no of electrons are " n "
n = Q / e
= 6.618 x 10-9 / 1.602 x 10-19
n = 4.131 x 1010 electrons
the gravitational force Fg = G m m / d2
= 6.67 x 10-11 x 0.052 x 10-6 / 0.0822
the gravitational force Fg = 2.4799 x 10-17 N
the electric force is FE = k q2 / d2
= 9 x 109 x ( 6.618 x 10-9 )2 / 0.0822
the electric force is FE = 5.862 x 10-5 N
the horizontal force is FH = m g tan6
= 0.05 x 10-3 x 9.8 x tan6
the horizontal force is FH = 5.15 x 10-5 N
the vertical force is = m g
= 0.05 x 10-3 x 9.8
the vertical force is FV = 4.9 x 10-4 N
