Answer
assertion is true but reason is false
Explanation
Assertion (A) is true because weight is defined as the gravitational force exerted by the Earth on a body :
where m is the mass and g is the acceleration due to gravity.
Reason (R) is false because mass is the measure of the quantity of matter and weight is the force due to gravity acting on that mass.
