Question

Two bodies of masses 100 kg and 1000 kg are at a distance 1 m apart . Calculate the gravitational field intensity and the potential at the middle point of the line joining them 

Answer 1

gravitational potential is =U= GM^2/r
here r=0.5m
Gravitational field intensity {E=Gm/r^2]
here r 1m

I hope this may help u...

Answer 2

Answer:

Explanation:

Gravitational field intensity exists as the strength of a gravitational field that is applied to a unit test mass. A gravitational force's intensity depends upon the source mass and the distance of the unit test mass from the source mass. The unit of gravitational field intensity exists N/Kg.

$\mathrm{M}_{1}=100 \mathrm{~kg}$

$\mathrm{M}_{2}=1000 \mathrm{~kg}$

$\mathrm{r}=1 \mathrm{~m}$

Gravitational potential at$\mathrm{X}=\frac{-\mathrm{GM}_{1}}{\mathrm{r} / 2}-\frac{\mathrm{GM}_{2}}{\mathrm{r} / 2}$

$=\frac{-2 \mathrm{G}}{\mathrm{r}}\left(\mathrm{M}_{1}+\mathrm{M}_{2}\right)$

$=\frac{-2 \times 6.67 \times 10^{-11}}{1}(100+1000)$

$=-1.46 \times 10^{-7} \mathrm{~J} /kg$

Hence, The  gravitational field intensity is $=-1.46 \times 10^{-7} \mathrm{~J} /kg$

The middle point of the line joining them is shown below,
