What is the value of escape velocity on a planet having radius 3 times that of Earth and on which acceleration due to gravity is three times that on Earth?

The escape velocity of that planet is three times of earth. as it is 11.2 km/s, it will be 3 × 11.2 = 33.6 km/s on that planet.

What will be the escape velocity on a planet which is having a radius 4 times that of Earth and the gravitational acceleration equal to the Earth?

2 km/s.

What planet mass is 100 times that of the Earth?

Question: The planet Saturn has 100 times the mass of the Earth and is 10 times more distant from the Sun than the Earth is. Compared to the acceleration (due to the Sun’s gravity)) at Earth’s location as it orbits the Sun, the acceleration (due to the Sun’s gravity at Saturn’s location as it orbits the Sun is A.

What will be the escape speed from a planet having mass 8 times that of Earth and diameter 4 times that of Earth?

= 11.2 km/s]

How many times more or less would you weigh if you could travel to a planet that has the same radius as the earth but one third the mass?

With eight times the volume, Earth’s radius would double. This means the gravitational force at the surface would reduce by a factor of (1/2)2 = 1/4, so a person would weigh only one-fourth as much.

What will be the escape velocity on some planets?

The escape velocity of Earth is 11.19 km/s. The escape velocity of Venus is 10.36 km/s. The escape velocity of Mars is 5.03 km/s. The escape velocity of Saturn is 36.09 km/s.

What is the reason for weightlessness in a satellite?

Reason of weightlessness in a satellite is Zero reaction force by satellite surface. Explanation: When satellite is moving with constant speed along the orbit, the satellite as well as the person inside it, both fall towards the earth with acceleration ‘g’.

Which planet do you think has the lowest escape velocity?

Pluto
Pluto is the smallest planet so it will have the least escape velocity.

Is there gravity on every planet?

Yes! Anything that has mass has gravity. The more mass something has (the bigger it is), then the more gravity it will have. So everything around us (including all the planets) have gravity!

What will be the escape speed from a planet having radius twice that of Earth?

5Km/s.

What will be the escape speed from a planet?
