For n = 2, l will have two values 0,1

For l = 0, ml = 0

l = 1, ml = -1,0,1

These are the possible combinations.

The n is the principal quantum number

l is the azimuthal quantum number

ml is the magnetic quantum number.

The formula to find the azimuthal quantum number is

l = 0,1,2,3 .......n-1

If n = 2, the azimuthal quantum number,

l = 0 , 1

Then, the ml can be found using the formula,

ml = 2l +1

For l = 0 , ml = 2(0) + 1

= 1

Therefore, ml will have only one value, which is 0

For l =1 , ml = 2(1) + 1

= 3

Therefore, the ml will have three values, they are -1,0,1

Answer:

The change in potential energy is $\Delta PE = - 3.8*10^{-16} \ J$

Explanation:

From the question we are told that

The magnitude of the uniform electric field is $E = 950 \ N/C$

The distance traveled by the electron is $x = 2.50 \ m$

Generally the force on this electron is mathematically represented as

$F = qE$

Where F is the force and q is the charge on the electron which is a constant value of $q = 1.60*10^{-19} \ C$

Thus

$F = 950 * 1.60 **10^{-19}$

$F = 1.52 *10^{-16} \ N$

Generally the work energy theorem can be mathematically represented as

$W = \Delta KE$

Where W is the workdone on the electron by the Electric field and $\Delta KE$ is the change in kinetic energy

Also workdone on the electron can also be represented as

$W = F* x *cos( \theta )$

Where $\theta = 0 ^o$ considering that the movement of the electron is along the x-axis

$\Delta KE = F * x cos (0)$

substituting values

$\Delta KE = 1.52 *10^{-16} * 2.50 cos (0)$

$\Delta KE = 3.8*10^{-16} J$

Now From the law of energy conservation

$\Delta PE = - \Delta KE$

Where $\Delta PE$ is the change in potential energy

Thus

$\Delta PE = - 3.8*10^{-16} \ J$

astraxan [27]

Hi there!

Recall the equation for weight.

$W = Mg$

W = Weight (N)

M = Mass (kg)
g = acceleration due to gravity (m/s²)

The weight of an object depends upon its MASS and the strength of the GRAVITATIONAL field. We can solve for weight:

$W = 1360 * 9.8 = \boxed{13,328 N}$
