NEET 2026 (Phase 1) · PhysicsCombinationsPrevious Year Question
Five capacitors of capacitances C1 = C² = C3 = C4 = 10 uF and C5 = 2.5 uF are connected as shown, along with a battery of 50 V. The equivalent capacitance and the charges on each capacitor respectively are:
Answer: (B) 5 uF, 125 uC on all capacitors. Answer: (b) Solution: The network reduces to C_eq = 5 µF.
- A.5 uF, 125 uC on C1 to C4 and 25 uC on C5
- B.5 uF, 125 uC on all capacitors✓
- C.5 uF, 250 uC on all capacitors
- D.4 uF, 250 uC on C1 to C4 and 125 uC on C5
Correct Answer
(B) 5 uF, 125 uC on all capacitors
Solution & Explanation
Answer: (b) Solution: The network reduces to C_eq = 5 µF. Total charge Q = C_eq·V = 5×50 = 250 µC; the series/symmetry of the arrangement gives 125 µC on each capacitor. → option (b).

PhysIn the following circuit, the equivalent capacitance between terminal A and terminal B is:PhysThe equivalent capacitance of the arrangement shown in figure isPhysThe equivalent capacitance of the system shown in the following circuit is:PhysThe equivalent capacitance of the combination shown in the figure is:PhysAn electric dipole with dipole moment 5 × 10⁻⁶ C·m is aligned with the direction of a uniform electric field of magnitude 4 × 10⁵ N/C. The dipole is then rotated through an angle of 60° with respect to the electric field. The change in the potential energy of the dipole is:PhysTwo identical charged conducting spheres A and B have their centres separated by a certain distance. Charge on each sphere is q and the force of repulsion between them is F. A third identical uncharged conducting sphere is brought in contact with sphere A first and then with B and finally removed from both. New force of repulsion between spheres A and B (radii negligible vs separation, treated as point charges) is best given as:PhysThe plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant K1 and K2 with thickness 3d/8 and d/2 respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If K1/K2 = 1.25, the value of K1 is:PhysA sphere of radius R is carved out of a uniform solid sphere of radius 2R (internally tangent, so its centre is at distance R from the big centre). The ratio of the moment of inertia of the small sphere to that of the remaining part, both about the Y-axis through the big sphere's centre, is:
