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- 13. 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.
