Which of the following statements are true? Check all that apply. Check all that apply. The gravitational force between two obje
2 answers:
Explanation:
The gravitational force acting between two masses is given by :;
Where
G is the universal gravitational constant
m₁ and m₂ are masses
d is the distance between masses
The correct statements are as follows :
1. The gravitational force between two objects is inversely proportional to the square of the distance between the two objects.
2. The gravitational force between two objects is proportional to the product of the masses of the two objects.
Hence, this is the required solution.

Answer:
Work done W =1406.25 J
Explanation:
Work done on a body can be calculated using newton's 2nd laws:
F=ma
Hence acceleration of the block is given by:
Displacement of the object is given by:
Substitute the values
Now work done is given by:
W=F.S
W = 25×56.25
W =1406.25 J
