Question

Two conductors having net charges of +20.0 µC and -20.0 µC have a potential difference of 20.0 V between them.
(a) Determine the capacitance of the system.
(b) What is the potential difference between the two conductors if the charges on each are increased to +400.0 µC and -400.0 µC?

Answer 1

Answer:

In order to estimate the frictional head loss in a pipe 1 m in diameter, through

which castor oil of specific gravity 0.96 and dynamic viscosity 9.9 poise, is to

be transported at the rate of 5000 litres per second, a test was conducted on

a pipe of diameter 50 mm using water at 15°C as the model fluid. Calculate

the discharge required for the model pipe.
