COMEDK · Physics · 18. Capacitance
In the figure below, the capacitance of each capacitor is \(3 \mu \mathrm{F}\). The effective capacitance between \(A\) and \(B\) is
- A \(3 \mu \mathrm{F}\)
- B \(5 \mu \mathrm{F}\)
- C \(6 \mu \mathrm{F}\)
- D \(\dfrac{3}{4} \mu \mathrm{F}\)
Answer & Solution
Correct Answer
(A) \(3 \mu \mathrm{F}\)
Step-by-step Solution
Detailed explanation
Let M be the intermediate node between the two middle capacitors. Between A and M: top capacitor and left-middle capacitor are in parallel: \(C_{AM} = 3 + 3 = 6\ \mu F\) Between M and B: right-middle capacitor and bottom capacitor are in parallel: \(C_{MB} = 3 + 3 = 6\ \mu F\)…

- A bullet, fired into a door gets embedded exactly at it's centre, causing the door to rotate about it's vertical axis, practically without friction, with an angular velocity of \(0.625\ rads^{-1}\). The door is 1.0 m wide and weighs 12 kg. If the mass of the bullet is 10g, find the speed with which it was fired. (Hint: The moment of inertia of the door about the vertical axis at one end is \(\dfrac{ML^2}{3}\)).COMEDK 2026 Medium
