Two particles of equal masses (m=5.5x10-15 kg) are released from rest with a distance between them equal to 1 m. if particle a has a charge of 12 μc and particle b has a charge of 60 μc, what is the speed of particle b at the instant when the particles are 3m apart?

To solve this problem it is necessary to apply the law of conservation of Energy and the law of Coulomb.

This way we have to

Where,

= Potential Electric Energy

Kinetic Energy

Therefore,

Replacing we have that

Therefore the speed of particle B at the instant is

mistakes are ok

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
