The mass of the earth is 6 × 10^(24) kg ...

The mass of the earth is `6 × 10^(24)` kg and that of the moon is` 7.4 xx 10^(22)` kg. If the distance between the earth and the moon is `3.84xx10^(5)` km, calculate the force exerted by the earth on the moon. (Take G `= 6.7 xx 10^(–11) N m^(2) kg^(-2)`)

Text Solution

AI Generated Solution

To calculate the gravitational force exerted by the Earth on the Moon, we can use Newton's law of universal gravitation, which states: \[ F = \frac{G \cdot m_1 \cdot m_2}{r^2} \] Where: - \( F \) is the gravitational force, - \( G \) is the universal gravitational constant, - \( m_1 \) is the mass of the first object (Earth), ...
