Answer: 0.048 J
Explanation:
The described situation is better understood with the attached figure.
Let's assume that when the mass is released after being lifted up, it starts performing simple harmonic motion with an amplitude L. Then, the maximum speed of this hanging mass is fulfilled at the equilibrium position and its given by the following equation:
(1)
Where:
is the spring constant which can be calculated by the Hooke's law: being the acceleration due gravity and the length the spring is streched.
is the mass
is the amplitude
So, (2)
Substituting (2) in (1):
(3)
(4)
On the other hand, the kinetic energy is given by the following equation:
(5)
(6)
Hence:
1-1
4-2
5-1
6-1

F = G m1*m2 / r^2 => [G] = [F]*[r]^2 /([m1]*[m2]) = N * m^2 / kg^2
That is one answer.
Also, you can use the fact that N = kg*m/s^2
[G] = kg * m / s^2 * m^2 / kg^2 = m^3 /(s^2 * kg)
The final magnification will be 400-fold or 400 times the original size of the object.
For magnifying smaller objects, a compound microscope is used.
A compound microscope consists of an objective and an eyepiece, whose diagram is shown in the adjoining image.
The lens near the object is called an objective and the other one is the eyepiece.
Let the magnification of the objective be m1
Let the magnification of the eyepiece be m2
The final magnification by the microscope, M, will be
M = m1 x m2
Putting the values in the above equation
M = 40 x 10
M= 400
Thus, the final magnification will be 400-fold or 400 times the original size of the object.
