What Determines the Direction of an Electric Field?

AI Thread Summary
An electric field is defined as a region where a charged body experiences an electric force, influenced by the presence of other charges. The direction of the electric field is determined by the force experienced by a positive test charge, which is a standard convention in physics. This means that the field points away from positive charges and towards negative charges. The confusion often arises from the distinction between the forces between unlike charges versus like charges. Understanding this convention clarifies how electric fields are represented and analyzed in physics.

I am a little confused with an electric field, Is it the kinda force between two particles positive and negative, or the force between two like charges? Then why is it that a positive charged particle can determine the direction of the field? i am a bit confused

thankyou

Well an electric field is defined as any region in which a charged body experiences an electric force. Convention. The convention that physicists use is that they use a +ve test charge to determine the direction of an electric field.

[Electric field strength is given by E=F/Q]
 

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...

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 .
