Charges Force Point Point charges

AI Thread Summary

To calculate the force on point charges 2Q and -Q/2, the formula F = k.q1.q2 / d^2 is used, where k is the electrostatic constant. The user initially finds the force on 2Q by summing the charges on the left side before applying the formula. For the charge -Q/2, the same approach applies, but it's important to consider that forces are vectors, which means both magnitude and direction must be accounted for. The discussion emphasizes the need to treat forces as vector quantities in calculations. Understanding these principles is essential for accurate force calculations between point charges.

Find the force on 2Q and -Q/22. Force between two point charges is given by : F = k.q1.q2 / d[2][/SUP]

The Attempt at a Solution

To find the force on 2q, I added the charges on left side and then calculated it using the formula.

But how do we do it for -Q/2.

Please guide me. Thanks

Same way. But we keep in mind that forces are vectors, with a magnitude and a direction.

Yeah. Thanks

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
