Any possibilities to become professor or researcher after getting 2nd class degree in mechanical engineer from 3rd grade unknown college?

In the question paper it is written as "g" not "rho". I think it is simply a symbol representing 1/separation distance. It isn't related to "rho".

The volume integral contains charge density divided by the separation distance, which gives potential.(since dpotential=kdq/r).

Write the notations properly on a page then send it.

It is given, it is 1/R= 1/|r-r'|

One over magnitude of separation distance

But you know voyager 1 will broke connection with earth by 2025(estimated)

Could someone kindly elaborate on the current trajectory of the Voyager 1 and 2 probes including their future destinations, the discoveries they are expected to make and the stars they are projected to pass by over the next time span of 5 billion years?

I love to read physics. I collect articles and make summary. If you find this helpful, please tell, it will encourage me.

I see, got it now!! I deeply appreciate your help, thank you!✨

It means this:
When you add up all the forces and they cancel each other out perfectly, then that means the Net force is zero.
.
.
No net force, means no acceleration.
No acceleration means no change in velocity.
.
.
So even with all the forces acting on the point, it won't affect the velocity.
The velocity will remain unchanged.

Can you explain this too, please? I couldn't comprehend the former.

Not necessarily.
If you consider a huge rock, and there are three people pushing it in the same direction to move out somewhere, then there are three concurrent forces.
But the net force is unbalanced.

Astronomy/Astrophysics

When net unbalanced force is zero, when concurrent forces act on a body, the object is in equilibrium.
Is this a correct statement?

Isn't it very basic question?

Astronomy/Astrophysics

Shouldn't it be ghi😭

I think it’s quit possible but unlike ring may be spherical shaped. Because from a level of atom to a huge galaxy everything has a center point and every other objects surrounds the center in all direction

Volume integral contains "volume charge density" as numerator right ?

If yes then are you sure you didn't wrote "rho" as "g" which equals 1/R in this case ? I am unable to understand the role of function "g = 1/R" here.

Taking f=V(x') (for the electrostatic potential E= -∇V) and g=1/R = 1/|r-r'|,

show that:
V(r)= ∭p(r')/R dv + (1/4)pi∬((1/R)∇'V(r')-V(r')∇'(1/R)) ds

Where ∇' means differentiation with respect to r'.

And ∭ represents volume integral where as ∬ represents surface integral.

If it's not a good university it's futile, that's the sad reality, your passion, perseverance mean nothing unless you meet the standards set by society

So, the statement "net unbalanced force is zero" signifies that it's balanced, isn't it?

Then isn't there any difference in the speed of entanglement??? , since for both observers time vary

Astronomy/Astrophysics

When net force is not zero, the net force is said to be unbalanced.
Or more specifically, there is a net unbalanced force acting on the system.
