Answer:
The new force becomes (1/9)th of the original force.
Explanation:
The gravitational force between two masses is given by :
Where
r is the distance between masses,
If the new distance is, r' = 3r
The new force is given by :
So, the new force becomes (1/9)th of the original force.
Answer:
0.7274 m
Explanation:
X denotes the distance from the reference point
M denotes the mass of the point
The center of mass of a system is given by
Taking the position of Juliet as the reference point
After the boat has moved the distance between the center of mass of the boat and the shore remains the same. The change is observed relative to the rear of the boat
The displacement of the boat towards the shore is
