Question

State whether the given statement is true or false:
The mass of a body can never be zero.
(A) TRUE
(B) FALSE

Answer 1

Hint:The mass of a body is the measure of the amount of matter present in it. The virtue of a body is only due to the matter present in it i.e. If there is no matter, a body itself would never have existed. Therefore, mass of a body can never be zero.

Complete step by step answer:
The mass of a body is defined as the amount of matter/number of particles present in a body. The mass of a body is an intrinsic property I.e. the mass of a body depends upon the body itself and it doesn’t depend upon any external factor.The SI unit for mass is Kg.
Therefore, the mass of a body is always constant and can never be zero.
Hence,the statement given in the question is true.
Additional information:
The weight of a body is the amount of gravitational force acting upon it. Hence, it can be zero or different at different positions depending upon its acceleration due to gravity.
The formula for weight of a body is given by: $W = mg$
Where, m is the mass of the body which is always constant and g is the acceleration due to gravity which is varying depending upon the conditions.
When acceleration due to gravity of an object is zero, as in case of free fall.
The weight of the body will also be zero: $W = mg = m \times 0 = 0$
The SI unit for Weight is same as force = $Newton\left( N \right)$

Note:The weight of a body can be equal to zero, but mass of a body can never be zero.The reason of the above statement is that weight of a body depends on the acceleration due to gravity and if it is zero then weight is also become zero while mass of a body doesn’t depend on such things and it is a intrinsic property of a body.Hence,it cannot be zero.
