If the electrons are attracted more by the nucleus because of an additional proton, what would happen to it?

Rus_ich [418]

Answer:

orbital speed of the electrons in their orbit will increase

Explanation:

As we know that centripetal force for electrons will be due to electrostatic attraction force of electron.

So it is given as

$F_e = F_c$

so we have

$\frac{(Ze)(e)}{4\pi \epsilon_0 r^2} = \frac{mv^2}{r}$

now on the left side if the force of attraction will increase and hence there must be the change in that part of equation

So here at the same position the speed of the electron

So we can say that correct answer will be

orbital speed of the electrons in their orbit will increase

A car moves 8 km from home to school and then back to the home. a) Calculate the Distance covered by this car. b) What is the Di

Sveta_85 [38]

Explanation:

Distance covered = Total distance travelled by the car

Since the car travels to school and back to home again,

Total diatance covered = 8 + 8 = 16km

Displacement = Shortest distance between start point and destination.

Since, the car returns back to home from school,

the start and destination point are same.

So Displacement = 0
