Question

An iron sphere and a wooden sphere, both of the same size, are immersed in water. The ratio of upthrust is:

• A. 2:1
• B. 1:2
• C. 1:1
• D. 3:1

Answer 1

The correct option is C

1:1

Since both the spheres have equal size so they have equal volume, so when they are immersed they will displace equal volume of fluid. So the upthrust will aslo be equal.
