The equivalent capacitance of this circuit is = 21F. That is option A.
<h3>Calculation of the equivalent capacitance</h3>
When capacitors are connected together in parallel the total or equivalent capacitance, CT in the circuit is equal to the sum of all the individual capacitors added together.
The four capacitors are 10 F, 3 F, 7 F, and 1 F.
Therefore the equivalent capacitance = 10 + 3 + 7 + 1=21F

Explanation:
Momentum before collision:
(2 kg) (4 m/s) + (5 kg) (-3 m/s) = -3 kg m/s
No external forces act on the balls, so momentum is conserved. Therefore, momentum after collision is also -3 kg m/s.
