Mass is not necessary the main thing we need is Displacement
As
Or
- Work done=Force×Displacement
The amount of work done is calculated as the force exerted to remove a object to D distance .
Since an alpha particle has 2 protons and no negative particles (electrons) to balance the net charge, its charge is
Q=2(1.6e-19)=3.2e-19C.
The force on a charged particle is F=QE so
(3.2e-19C)(600N/C)=1.92e-16N
2. The dryer sheet is negatively charged and your hand is positively charged
Water freezes at the freezing point to ice then melts to the melting turning it to liquid and vapor causing gas in precipitation
1) Refraction
2)Reflection
3)Concave
4)Convex
I took the test and got this right so you can believe me :)
Hope this helps
