Question

two objects in the two pans of a balance are such that the two pans remain stationary at the same height, why do we say that their masses are equal ​

Answer 1

Answer:

because the force applied by the two masses downwards are equal

Explanation:

let the masses be m1 and m2

then the force applied by them on the pan=m1a and m2a (acceleration g is same)

so m1a must be equal to m2a as the forces are cancelling each other to keep the pans in equillibrium
