The center of mass "represent the unique point in an object or system which can be used to describe the system's response to external forces and torques"
The center of mass on a two dimensional plane is defined with the following formulas:
Where M represent the sum of all the masses on the system.
And the center of mass C.M
represent the masses.
represent the coordinates for the masses with the units on meters.
So we have everything in order to find the center of mass, if we begin with the x coordinate we have:
For this case we have an additional mass and we know that the resulting new center of mass it at the origin C.M and we want to find the location for this new particle. Let the coordinates for this new particle given by (a,b)
Option 3 is the correct option to the following question.
Double slit experiment:
The double-slit experiment in modern physics reveals that light and matter can exhibit characteristics of both classically described waves and particles; it also shows the inherently probabilistic existence of quantum mechanical phenomena.
When two wavelength meets ,if the resultant amplitude is maximum then this is known as constructive interference and the resultant amplitude is maximum then this is known as destructive interference.
To evaluate this composition, you need to find the value of function f first, BUT, f(0) is 1 over 0, and division by 0 is undefined. Therefore, you cannot find the value of this composition. It's unrecognizable.
