If the distance between two objects decrease and the masses of the objects remain the same, then the force of gravity between the two objects
<u>Answer:</u>
increases
Explanation:
The formula of gravitational force is given as:
F=G Mm/r^2
G = gravitational constant
M, m = Masses of two different objects in which the force is acting.
r = distance between both the objects.
As we can see from the formula that the force of gravity is inversely proportional to the square of the distance between both objects.
When the distance between both objects with the same masses decreases the gravitational force between them increases. Hence the correct answer is option B.

Answer:
Explanation:
From the question we are told
The amplitude of the lateral force is 
The frequency is 
The mass of the bridge per unit length is 
The length of the central span is 
The oscillation amplitude of the section considered at the time considered is 
The time taken for the undriven oscillation to decay to
of its original value is t = 6T
Generally the mass of the section considered is mathematically represented as

=> 
=> 
Generally the oscillation amplitude of the section after a time period t is mathematically represented as

Here b is the damping constant and the
is the amplitude of the section when it was undriven
So from the question

=> 
=> 
=> 
=> 
Generally the amplitude of the section considered is mathematically represented as

=> 
=> 
=> 
=>
