Statement A: A person will weigh more in Ooty than in Delhi
The statement A is incorrect.
Weight is a measure of the force exerted on an object due to gravity, and it is directly proportional to the mass of the object. In simpler terms, weight is the measure of how heavy an object is. The weight of an object can vary depending on the gravitational force acting on it.
In Ooty, which is a hill station located at a higher elevation, the gravitational force is slightly weaker compared to Delhi, which is located at a lower elevation. Therefore, a person will actually weigh slightly less in Ooty compared to Delhi.
It is important to note that the mass of an object remains the same regardless of the location. Mass is a measure of the amount of matter in an object and is independent of the gravitational force acting on it.
Statement B: Mass is measured by pan balance and weight is measured by spring balance
The statement B is correct.
A pan balance is a type of balance that allows the comparison of the masses of two objects. It is commonly used to measure mass by balancing an unknown mass against known masses.
On the other hand, a spring balance, also known as a weighing scale, measures the weight of an object. It works based on Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement of the spring.
So, while mass can be measured using a pan balance, weight is measured using a spring balance.
In conclusion, statement A is incorrect because a person will weigh less in Ooty than in Delhi due to the weaker gravitational force. Statement B, on the other hand, is correct as mass is measured by a pan balance and weight is measured by a spring balance.
