Question

The magnitude of zero error of the spring balance and least count of the measuring cylinder, shown here, are, respectively: (1) 2.5 g and 0.1 mL (2) 5.0 g and 0.1 mL (3) 2.5 g and 0.2 mL (4) 5.0 g and 0.2 mL

Answer 1

 Answer: (4) For the spring balance: Each small division = It can be observed that the zero error of the spring balance is equal to two small divisions. Two small divisions = 2 × 2.5 g = 5.0 g
Therefore, the zero error of the spring balance is 5.0 g. For the measuring cylinder: The least count of the measuring cylinder is the least measurement that can be measured by the device. Each small division = Therefore, the least count of the measuring cylinder is 0.2 mL.
