When a proton and an electron are placed equidistant from a point charge, they experience equal magnitudes of force but in opposite directions due to their opposite charges. The direction of the force on a charged particle in an electric field depends on the sign of the charge; positive charges move toward negative charges and vice versa. Although both particles experience the same force, the proton's greater mass results in slower acceleration compared to the electron. The physical size of the charge does not affect the forces, as all charges behave as point charges located at their centers. Understanding these principles clarifies the comparison of forces acting on the proton and electron.

I am studying Physics, which I can usually understand, but the chapter
on Electricity is totally confusing to me. Can anyone help with this
question:
At different times, a proton and electron are placed equidistant from a
point charge. How do the magnitudes and directions of the forces acting
on them compare? Why?

Thanks

If you put a charged particle in an electric field, what determines the direction of the force on that charged particle? Does it matter if the charge is positive or negative? How does the charge on the proton compare to the charge on the electron?
 
well, obviously they will move in opposite directions due to equal but opposite charge. However, the proton, being much heavier, will move slower as teh same force on a particle with more inertia will have less effect.

The physical size (volume) of the charge does not matter. All charges act as though they were point charges located at their centres (the geometrical centre of charge, that is). What matters is the type of charge (+ or -) and the distance between the centres of the charges. Does that help you compare the direction and magnitude of the forces?

The acceleration of a proton would be less than that of an electron, but that isn't what it is asking for.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
