Question

If weight of a body is 1000 dyne, then the mass of the body will be(take g = 10ms${}^{-}$ ${}^2$)

• A. 10${}^{-}$ ${}^1$kg
• B. 10${}^{-}$ ${}^2$kg
• C. 10${}^{-}$ ${}^3$kg
• D. 10${}^{-}$ ${}^4$kg

Answer 1

The correct option is C 10${}^{-}$ ${}^3$kg

1dyne=${10}^{-5}N$

1000dyne=${10}^{-2}N$

${10}^{-2}N$=mg

m=$\frac{{10}^{-2}}{10}{=10}^{-3}kg$
