Question

The ratio of gravitational force on Neptune to the Gravitational force of earth is 9:8.
Abdul weights 792 N on earth , Calculate his weight on Neptune.​

Answer 1

$\huge \green{\bf Solution :-}$

$\blue{\rm Given :-}$

• Gravitational force of Neptune : Gravitational force of Earth = 8 : 9

Now,

Let the Gravitational force of Neptune and Gravitational force of Earth be $\red{\bf W _ N}$ and $\red{\bf W _ E}$ respectively.

• Weight of Abdul on Earth = 792 N

Therefore,

$: \implies \dfrac{\orange{\rm W _ N}}{\orange{\rm W _ E}} = \red{\dfrac{9}{8} }$

$: \implies \dfrac{\orange{\rm W _ N}}{ \orange{792}} = \red{\dfrac{9}{8} }$

$: \implies \dfrac{\orange{\rm W _ N}}{ \orange{792}} = \red{\dfrac{9}{8} }$

$: \implies \purple{ {{\rm W _ N}} = {\dfrac{9}{8} \times 792}}$

$: \implies \purple{ {{\rm W _ N}} = 9 \times 99 }$

$: \implies \purple{ {{\rm W _ N}} =891 }$

Thus, the weight of Abdul on Neptune is 891 N

Hence, Solved ♡

Answer 2

Answer: chill bro its ez

Explanation:

Neptune:9

earth:8

mass of object or abdul:792N

weight on neptune :

Wn/we

i.e weight on neptune/weight on earth

Wn/We= 9/8

Wn/792= 9/8

Wn= 9/8*792

so, Wn = 9*99   because 792 gets divided by 8 and quotient is 99 so 9*99

therefore, Wn = 891N

easy hai na  :)
