Question

A cubical block of wood of density 5g cm ^-3 stand on the table of 10cm .Find the Thrust by the block of wood on the table ,if g = 10 m‐²​

Answer 1

Explanation:

Side a = 10cm = 0.1m

So Volume = a

3

=0.001m

3

orV=1000cm

3

.

So mass = 5g/cc×1000cc=5000gm=5kg

hence upthrust = 5kg×g=50N.
