Question
A rain drop of mass $0.1 \mathrm{~g}$ is falling with uniform speed of $10 \mathrm{~cm}^{-1}$. What is the net weight of the drop?(a) $10^{-2} \mathrm{~N}$(b) $10^{-3} \mathrm{~N}$(c) $2 \times 10^{-3} \mathrm{~N}$(d) zero
Step 1
- Mass of the raindrop, \( m = 0.1 \, \text{g} = 0.1 \times 10^{-3} \, \text{kg} = 10^{-4} \, \text{kg} \) (since 1 g = \( 10^{-3} \) kg). - Speed of the raindrop, \( v = 10 \, \text{cm/s} = 0.1 \, \text{m/s} \) (since 1 cm = 0.01 m). Show more…
