A 10g mass is suspended from a string and immersed in a beaker of liquid(Weight of beaker and liquid = 500g). A boy hold the string with his hand not letting the 10g mass touch the bottom of the beaker. (let upthrust generated by mass be X newton.) Qn: what would be the reading on the weighing scale? The boy repeat the process again and this time round, he let the 10g mass sits on the bottom of the beaker. Qn: Would there be any change of reading in the weighing scale?
