Hi there i was thinking about this question but i can't get the solution for solving it

The question is:-
A number of capacitors each of 2µF are connected as shown in the figure given below:
(Please open the link below)

What is the net capacitance between A & B?

A. 2µF
B. 4µF
C. 6µF
D. 10µF
The equations for series and parallel combinations of capacitance are:
Parallel; C=1/C1+1/C2
Series; C=C1+C2

i don't know how to use these equations for getting final answer

Your formulas are incorrect. After you correct those, the trick is always to look for the simplest combination to combine. Come back with some work.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
