A proton with kinetic energy of 1.16×105 eV is fired perpendicular to the face of a large plate that has a uniform charge densit
Nezavi [6.7K]

Answer:

force on the proton = 5.96 × 10^{-14} N

Explanation:

given data

kinetic energy = 1.16 ×10^{5}  eV

charge density of σ = +6.60 μC/m²

solution

we get here force on the proton that is express as

F = qE  ....................1

here q is charge on proton i.e = 1.6 × 10^{-19} C

and E is electric field due to charge i.e E = \frac{\sigma }{2*\epsilon_o }

so put the value in equation 1 we get

force on the proton = 1.6 × 10^{-19} × \frac{6.60*10^{-6}}{2*8.85*10^{-12}}  

force on the proton = 5.96 × 10^{-14} N

Eddi Din [679]

Answer:

7m

Explanation:

5+2=7 and then I added in the "m" and got 7m, so presumably g=7m.

A charge of 5.4 C experiences a force of 25.0 in an electric field. What is the strength of electric field at that point ? If th
Airida [17]

The strength of the electric field at that point and the force would this charge experiences at that point will be 4.587 N/C and  12.38 N.

<h3></h3><h3>What is the electric field strength?</h3>

The electric field strength is defined as the ratio of electric force to charge.

Given data;

q₁ = 5.4 C

F₁ is the electric force in case1

E is the electric field =?

F₂ is the electric force in case 2

q₂ is the charge 2

The strength of the electric field at that point is;

F₁=Eq₁

E₁=F/q₁

E₁=25.0 N / 5.4 C

E₁=4.587 N/C

The force would this charge experience at that point when the charge is 2.7 C;

F₂=Eq₂

F₂=4.587 N/C × 2.7 C

F₂ = 12.38 N

Hence the strength of the electric field at that point and the force would this charge experiences at that point will be 4.587 N/C and  12.38 N.

What is velocity in science
katovenus [111]

Answer:

Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

Hope this helps! ^-^
