A body of mass 60g60g experiences a gravitational force of 3.0N3 . 0N, when placed at a particular point. The magnitude of the gravitational field intensity at that point is

Options

  1. A50Nkg−150N{kg}^{- 1}
  2. B20Nkg−120N{kg}^{- 1}
  3. C180Nkg−1180N{kg}^{- 1}
  4. D0.05Nkg−10 . 05N{kg}^{- 1}

Correct answer

A. 50Nkg−150N{kg}^{- 1}

Step-by-step solution

∵∵ Gravitational force, FG=Eg×m{F}_{G} = {E}_{g} \times m, where Eg={E}_{g} = Gravitational field at the given point.

Eg=FGm=360×10−3=50Nkg−1{E}_{g} = \dfrac{{F}_{G}}{m} = \dfrac{3}{60 \times {10}^{- 3}} = 50N{kg}^{- 1}
