Question

13. Find the equivalent capacitance between
P and Q. Given, area of each plate = A
and separation between plates = d.​

Answer 1

Explanation:

Calculate the dE/dt, the time rate of change of the electric field between the plates

Some scales, such as the traditional beam balance, measure mass directly by counteracting the downward force by another equal downward force on the opposite side of the pivot. On a beam balance, you add enough mass to the opposite pan to counterbalance the unknown mass. No force is measured.
