NEET 2019 Odisha · PhysicsMeter bridgePrevious Year Question
A metre bridge is balanced with P/Q = l/l. If the positions of galvanometer and cell are interchanged, will it balance, and what is the condition?
Answer: (D) yes, P/Q = l/l. \textbf{Answer:} (4) yes, P/Q = l/l \textbf{Solution:} Interchanging the cell and galvanometer branches leaves the balance condition unchanged: P/Q = l/l.
- A.yes, P/Q = (100 − l)/(100 − l)
- B.no balance
- C.yes, P/Q = l/l
- D.yes, P/Q = l/l✓
Correct Answer
(D) yes, P/Q = l/l
Solution & Explanation
\textbf{Answer:} (4) yes, P/Q = l/l \textbf{Solution:} Interchanging the cell and galvanometer branches leaves the balance condition unchanged: P/Q = l/l.

PhysIn a metre bridge experiment, the positions of the cell E and galvanometer G are interchanged. In the galvanometer we shall observe:PhysA resistance wire in the left gap of a metre bridge balances a 10 resistance in the right gap at a point dividing the wire 3:2. If the wire length is 1.5 m, the length corresponding to 1 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:PhysThe Sun rotates once in 27 days. If it expanded to twice its present radius (uniform-density sphere, no external influence), its new period would be about:PhysA uniform rod of mass 20 kg and length 5 m leans against a smooth vertical wall, making 60° with the wall; its lower end rests on a rough horizontal floor. The friction force exerted by the floor is: (g = 10 m/s²)
