Question

A solid of mass 1.3kg suspended by a string,is completely immersed in water. If tension in the string is 6.0. Find the upthrust of the solid

Answer 1

1.3 * 9.8 - 6.0 = ____

actually, the weight of the solid is pushing down. Any upthrust is provided by the water displaced.

Answer 2

6•74

Answer 3

7N

Answer 4

mass of a solid is= 1.3kg
tension of a solid =1.3*10=13N
tension of the spring=6.0N
since is completely immersed in water the upthrust in the solid= tension of a solid- tension of the spring
U=13-6=7N
