Question

the mass and diameter of the Planet are twice of thoseof the earth what will the acceleration due to gravity at the planet if acceleration due to gravity of the Earth is g​

Answer 1

Gravitational acceleration, g∝M
p
​
and g∝
r
p
2
​

1
​

where M
p
​
is mass of planet and r
p
​
is the radius of the planet

So,
g
e
​

g
p

1
​


Time period of pendulum, T∝
g
​

1
​


Thus time period of pendulum at the other planet will be
2
​
times its period
Answer is root 2 bro
I guess thid helped you friend
Thank you

Answer 2

Answer:

2G

Explanation:

because mass is directly proportional to the acceleration due to gravity
