Initial water mark on cylinder = 30ml
final water mark on cylinder = 38ml
volume of water displaced = 38 - 30 = 8ml

8ml = 8cm³
density of water = 1g/cm³
mass of water displaced = density*volume = 1 *8 = 8g = 0.008 kg

loss of weight = weight of water displaced = 0.008*9.8 N =0.0784 N
Loss of weight is same as the buoyant force.
So buoyant force is also 0.0784N
seriously??????
oh..
yeah..seriously!! you can check it..
fine and thanks
see some example with iron ball and wooden object.

The loss of weight will be equal to the buoyant force so the answer is 0.0784N
