The electrostatic force on the electron is given by
F=qE
where q is the electron charge and E the intensity of the electric field.

So, in order to find E, we just need to re-arrange the formula and use F=1.5 \cdot 10^{-14} N:
E= \frac{F}{q} = \frac{1.5 \cdot 10^{-14}N}{1.6 \cdot 10^{-19}C}=9.4 \cdot 10^4 N/C

So, the correct answer is C.

Two spherical shells have a common center. A -1.50 × 10-6 C charge is spread uniformly over the inner shell, which has a radius
Murrr4er [49]

Answer:

a) At 0.20 m, the magnitude of the field is 675.0 kV

The direction of the field is acting outwards from the center of the charged spheres

b) At 0.10 m, the magnitude of the field is 135 kV

The direction is acting outwards from the center of the charged spheres

c) At 0.025 m

The magnitude of the field, V = -270.0 kV

The direction of the field is inwards, towards the center of the charged spheres

Explanation:

The charged spherical shell parameters are;

The charge on the inner sphere, q₁ = -1.50 × 10⁻⁶ C

The radius of the inner shell, R₁ = 0.050 m

The charge on the outer sphere, q₂ = +4.50 × 10⁻⁶ C

The radius of the outer shell, R₂ = 0.15 m

Let 'r', represent the distance at which the electric field is measured, the following relationships can be obtained;

When r < R₁ < R₂,

V = k \cdot \left( \dfrac{q_1}{R_1} + \dfrac{q_2}{R_2} \right )

When R₁ < r < R₂,

V = k \cdot \left( \dfrac{q_1}{r} + \dfrac{q_2}{R_2} \right )

When R₁ < R₂ < r,

V = k \cdot \left( \dfrac{q_1  + q_2}{r^2}  \right )

a) When r = 0.20 m, we have;

R₁ < R₂ < r, therefore

V = k \cdot \left( \dfrac{q_1  + q_2}{r^2}  \right )

By plugging in the values, we get;

V = 9 \times 10^9 \times \left( \dfrac{-1.50 \times 10^{-6} + 4.50\times 10^{-6} }{0.20^2}  \right ) = 675.0 \ kV

Therefore, the magnitude of the field, V = 675.0 kV

The direction of the field is outwards

b) When r = 0.10 m, we have;

When R₁ < r < R₂, therefore;

V = k \cdot \left( \dfrac{q_1}{r} + \dfrac{q_2}{R_2} \right )

By plugging in the values, we get;

V = 9 \times 10^9 \times \left( \dfrac{-1.50 \times 10^{-6}  }{0.10}  + \dfrac{4.50\times 10^{-6}}{0.15} \right ) = 135 \ kV

Therefore, the magnitude of the field, V = 135 kV

The direction of the field is outwards from the center

c) When r = 0.025 m, we have;

When r < R₁ < R₂, therefore;

V = k \cdot \left( \dfrac{q_1}{R_1} + \dfrac{q_2}{R_2} \right )

By plugging in the values, we get;

V = 9 \times 10^9 \times \left( \dfrac{-1.50 \times 10^{-6}  }{0.05}  + \dfrac{4.50\times 10^{-6}}{0.15} \right ) = -270 \ kV

Therefore, the magnitude of the field, V = -270.0 kV

The direction of the field is inwards, towards the center of the charged spheres.

What determines the frequency of an electromagnetic wave
Ostrovityanka [42]

<h2>The frequency depends upon the source energy of electromagnetic waves</h2>

Explanation:

The energy of electromagnetic  wave is

E  = h ν

E is the energy of source emitting the waves

here h is Plank's constant

and ν is used for the frequency of the electromagnetic wave

Thus the frequency of wave depends upon the energy of electromagnetic source . Because h is constant .
