Gravitational force on an imaginary planet is 6 times stronger than the gravitational force of the earth. Determine the value of acceleration due to gravity and weight of an object of mass 50 kg on that planet…

On the surface of a planet, a body experiences force as :

Newtons' gravitational force = F = G M m / R²
= m g'
where G = Universal gravitational constant.
M = mass of planet
m = mass of the object/body
R = radius of planet.

This force is called its weight or m g' on that planet.

So acceleration due to gravity on a planet = g'
g' = gravitational Force / mass

As the mass is same on both planets (mass is the amount of matter)
then g' = 6 * force on Earth / mass
= 6 * acceleration due to gravity on Earth
= 6 * 9.8 m/s² = 58.8 m/s²

weight of object = mass * g' = 50 kg * 58.8 m/sec²
= 294 Newtons.

Also it is represented by a unit called kg-f or kg-wt
that means mass is multiplied by acceleration due to gravity.

On that planet, the weight is = 50 kg-wt. or 50 kg-f. as kg-f on that planet is 6 times kg-f on Earth.

GovindKrishnan: So, sir can we multiply weight on earth with 6 as g on that planet is 6 times earth's g?

GovindKrishnan: The object's weight on earth is 50kg (given)

kvnmurty: For me, i will not write the weight of the object as 294 kg or 50*6 kg... I will not do that...

kvnmurty: for me: weight always remains 50 kg (or 50 kg-f or 50 kg-wt) on any planet ... but in terms of Newtons, the number will change depending local value of g.

kvnmurty: when you say weight = 50 kg, you r telling that mass is 50 kg and multiply it with local value of g.

kvnmurty: others may have a different view.. i dont agree

qais: thanks sir :)

kvnmurty: my weight in free space is 60kg-wt or equal to 0 N, on Earth is 60 kg or 60 kg-wt or 600N, on Moon is 60 kg-wt. or 100 Newtons. On moon also i will say my weight is 60 kg.. but when calculated in Newtons, i say 100 N.

kvnmurty: when i say weight is 60 kg => means 60 kg-wt.. and also it means that mass is 60 kg... two things are told by same sentence.

GovindKrishnan: Thank u very much sir…

Answer:

On the surface of a planet, a body experiences force as :

Newtons' gravitational force = F = G M m / R²

= m g'

where G = Universal gravitational constant.

M = mass of planet

m = mass of the object/body

R = radius of planet.

This force is called its weight or m g' on that planet.

So acceleration due to gravity on a planet = g'

g' = gravitational Force / mass

As the mass is same on both planets (mass is the amount of matter)

then g' = 6 * force on Earth / mass

= 6 * acceleration due to gravity on Earth

= 6 * 9.8 m/s² = 58.8 m/s²

weight of object = mass * g' = 50 kg * 58.8 m/sec²

= 294 Newtons.

Also it is represented by a unit called kg-f or kg-wt

that means mass is multiplied by acceleration due to gravity.

On that planet, the weight is = 50 kg-wt. or 50 kg-f. as kg-f on that planet is 6 times kg-f on Earth.

Please brainlest me the answer

Hope its help. You
