Net Force of A: Diagram Analysis
AI Thread Summary
To find the net force on object A, the relevant equations include the force between charges FAB=KqAqB/r², and the components of the forces Fx=Fcosθ and Fy=Fsinθ. The total force can be calculated using the formula FR=sqrt(Fx² + Fy²) and determining the angle θ with θ=tan⁻¹(Fy/Fx). Participants are encouraged to calculate the vector forces F_AB and F_AC, then sum these vectors to obtain the total force acting on A. Providing the calculations will help clarify the process.

You need to find the vector forces ## F_{AB} ## and ## F_{AC} ## and sum those force vectors to get the total force on A. Can you show us your work on that?Spotify said:
Here is what I tried
This question was actually asked in one of our engineering entrances.
The answer was 1D.
My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance)
My thoughts for the first case , one of them must be 12 volt while the other is 0
The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
The answer to this question is statements (ii) and (iv) are correct.
(i) This is FALSE because the speed of water in the tap is greater than speed at the water surface
(ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not?
(iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
