Question:
The universal constant of gravitation G has the unit
The universal constant of gravitation G has the unit
Options:
- a) N
- b) m/s
- c) Joule
- d) Nm2 / kg2
- a) N
- b) m/s
- c) Joule
- d) Nm2 / kg2
correct answer : d)
Explanation:
The unit of G is derived from F = G * m1 * m2 / d^2 => G = F * d^2 / (m1 * m2), which gives Nm2 / kg2.
The unit of G is derived from F = G * m1 * m2 / d^2 => G = F * d^2 / (m1 * m2), which gives Nm2 / kg2.
