Question

1.9
A system has two charges qA = 2.5 x 10'C and 93
= -2.5 x 10-7 C
located at points A: (0.0.-15 cm) and B: (0,0. +15 cm), respectively.
What are the total charge and electric dipole moment of the system?
1.10 An electric dipole with dipole moment 4 x 10°C m is aligned at 30°
with the direction of a uniform electric field of magnitude 5 x 104 NC !
Calculate the magnitude of the torque acting on the dipole.
1.11 A polythene piece rubbed with wool is found to have a negative
charge of 3 x 10-7 C.
(a) Estimate the number of electrons transferred (from which to
which?)
(b) Is there a transfer of mass from wool to polythene?​
