Q1 · Prescribed Experiments · EASY
In a vernier caliper, 10 vernier scale divisions coincide with 9 main scale divisions. If the smallest division on the main scale is 1 mm, the least count is
Q2 · Prescribed Experiments · EASY
In a simple pendulum experiment, the time period is measured for different lengths. The graph of T² versus L is expected to be
Q3 · Prescribed Experiments · HARD
In a resonance tube experiment, the first and second resonances are obtained at lengths 25 cm and 75 cm respectively. The end correction of the tube is
Q4 · Prescribed Experiments · HARD
In an experiment to verify Ohm's law using a potentiometer, the balancing length for a cell of emf E is found to be 350 cm. When a resistor of 10 Ω is connected across the cell, the balancing length becomes 300 cm. The internal resistance of the cell is
Q5 · Prescribed Experiments · MEDIUM
In a screw gauge, the pitch is 1 mm and there are 100 divisions on the circular scale. The least count of the screw gauge is
