Question

A metallic sphere of radius 2cm is completely dipped in water find the force of buoyancy if density of water is 1000kg m3
​

Answer 1

Answer:0.33N

Explanation:

Radius of the sphere=2 cm=0.02m

1. volume of solid sphere=4/3×π×r³
2. 4/3×3.14×(0.02)³=33.5×10⁻⁶m³
3. force buoyancy=density of water×volume of immeresed×acceleration due to gravity
4. f=1000×9.8×33.5×10⁻⁶
5. 0.33N
