    Coulomb's law Law
AI Thread Summary
Coulomb's Law can be applied to calculate the force between two charged objects, with charges of 5 Coulombs and 7 Coulombs separated by 5 meters, resulting in a force expressed as F = k(5C*7C)/5m². The gravitational force between the same objects, with masses of 5kg and 7kg, can also be calculated using Newton's law of universal gravitation, which is similar in form to Coulomb's Law. Since both charges are positive, they will repel each other, indicating that the net force will be directed away from one another. The discussion also touches on the electrical potential field experienced by a charge of 25 Coulombs under a force of 9 Newtons. Understanding both laws is essential for solving these types of physics problems effectively.

Using Coulomb's Law, find the force between two objects that have charges of 5 Coulombs and 7 Coulombs, respectively. They are separated by a distance of 5 meters. For the same objects, one of which has a mass of 5kg and the other has a mass of 7kg, what is the force of gravity between them if they are also 5 meters apart? If the charges are both positive, what is the net force between them and in what direction will they initially be accelerated: toward each other or away?

Could somone help me with this question with explanations?

Would really appreciate it!

F= k(5C*7C)/5meters

Obviously I have to use Coulomb's law. I am not sure how to integrate the masses of each object into the equation. The answer will be in Newtons. Since they are both positive charges they will be accelerating away from each other.

The separation distance is squared in Coulomb's Law.

Do you know Newton's law of universal gravitation ? It looks much like Coulomb's Law, with the masses replacing the charges. The constants are very different.

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
