To solve this problem we will apply the Newtonian concept of gravitational acceleration produced by a planet. This relationship is given by:
Where,
G = Gravitational Universal Constant
M = Mass of Earth
r = Radius
The values given are based on the constants of the earth, so they can be expressed as
The relationship of gravity would then be given:
The relationship with the new planet, from the gravity of the earth would be given
The relationship with the weight of the earth would be given as:
Therefore the weigh on this planet would be 96N
Answer:
Explanation:
Suppose when bucket is half full it has a mass of 2 m rotating in a circle of radius r
When Bucket is quarter full then it has a mass of m rotating in a circle of radius r.
When an object moves in a circular path then it experiences an inward force which is given by
where v=velocity of bucket
Force in case 2 is given by
Thus
therefore force required in half bucket is more than force required in quarter bucket full.
