EXP to determine the mass of two different object using beam balance
CLASS 11 PHYSICS EXP cn anyone send me the observation of this exp
Answers
Answer:
body with a gravitational mass m1 is placed in the left pan and a standard weight of m2 is placed in the right pan to keep the beam horizontal for a beam balance, a1 = a2, then m1 = m2. In other words, the gravitational mass of the body in the left pan = the gravitational mass in the right pan.

To Determine The Mass Of Two Different Objects Using A Beam Balance
Theory
A physical balance determines the gravitational mass of a body by making use of the principle of moments.
Load × Load arm = Effort × Effort arm
m1g × a1: m2g × a2
m1a1 = m2a2
A body with a gravitational mass m1 is placed in the left pan and a standard weight of m2 is placed in the right pan to keep the beam horizontal for a beam balance, a1 = a2, then m1 = m2.
In other words, the gravitational mass of the body in the left pan = the gravitational mass in the right pan.
Procedure
Adjust the physical beam. When the beam is in the raised position, the pointer will stay at rest and coincide with the zero division or moves to and fro over the scalp, equally over the zero division.
When the beam is in the rest position, put any one of the objects in the left pan. Now put some standard weights with half of the forceps from the weight box. Shut the front glass door in order to avoid the air current disturbance. Raise the beam with the help of handle and make sure that the beam is horizontal and the pointer moves to and fro equally on both sides of zero division. If not, put or remove some weight to get the correct horizontal position of beam and pointer.
Repeat step 2 for the second object.
