Experiment with an Electroscope, a Charged Rod and my hand

AI Thread Summary
When a positively charged rod is brought near an electroscope, the charges within the electroscope separate, causing the leaves to repel each other. If the positively charged rod is then touched with a hand, it likely grounds the rod, allowing electrons to flow from the hand to the rod. This results in the electroscope becoming negatively charged, as the leaves, initially positively charged, will now repel each other more strongly due to gaining negative charge. After removing the hand and rod, the electroscope retains a negative charge. Ultimately, the electroscope ends up negatively charged due to the grounding effect.

Homework Statement
We bring a positively charged rod closer to the electroscope what happens if we touch the positively charged rod with our hands and then move the hand and rod away?

I know that if we bring a positively charged rod closer to the electroscope, charges of electroscope are separated and the leaves of the electroscope get away from each other. but what happens if we touch the positively charged rod with our hands and then move the hand and rod away?

What do you think happens ? Bear in mind that "touch the positively charged rod" probably means you've grounded the rod.

Thank you.
I think electroscope charge will be - in the end.
 
Why ?

Because at first, the rod approaches the electroscope with a positive charge, so the conductor sphere has a negative charge and the leaves have a positive charge. when we touch the rod the leaves are repelled and negatively charged, so the distance between them is reduced and after colliding with each other, they are charged with the same charges (both negative charge) and repel each other.
 

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 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
