solve q -13 please solve with detail explaination charge 10¯7 C stay in limiting equilibrium on a
horizontal table with a separation of 10 cm
between them. The coefficient of friction between
each particle and the table is the same. Find the
[Ans. = 0•181
value of this coefficient.
o small spheres each of mass 10¯6 kg are sus-
nded from a point by silk threads 50 cm long.
They are equally charged and repel each other to
a distance 20 cm apart. Calculate charge on each.
Take g = ms-2.
[Ans. 2-98 x 10-9
14 Two point charges q2 = 3 x 10-6 C and ql = 5 x
10-6 C are located a
