What is a "g" for electric fields?

AI Thread Summary
A "g" is a unit of acceleration, specifically the acceleration experienced by a mass in free fall near Earth's surface, equivalent to 9.80665 m/s². The discussion clarifies that "g" is not a unit of force but rather measures the acceleration a body feels when subjected to forces. The context involves calculating the electric field strength at a point where a proton experiences an acceleration of 1 million "g's." Participants emphasize the distinction between force and acceleration in this context. Understanding "g" is crucial for accurately interpreting concepts related to electric fields and forces.

What is a "g"?

What is the electric field strength at a paoint in space where a protone (m=1.67x10^-27 kg) experiences an acceleration of 1 million "g's"?

My only question is:
What is a "g"?
 
Physics news on Phys.org
Its a unit of force equal to the force exerted by gravity. Its basically the amount of force a body feels when its accelerated.

No, it is a unit of acceleration, not a unit of force.

It is the acceleration of a mass falling freely near the Earth's surface (with no air resistance, etc).

1g = 9.80665 m/s^2.
 
Thanks guys. I can't believe I didn't know that "g" meant gravity.
 

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 '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...
