A proton is shot perpendicularly at an infinite plane of charge. The charge density of the plane is +7.65×10^−4 C/m^2. If the pr

Alexeev081 [22]

Answer:

The velocity is $2.94\times10^{6}\ m/s$ .

Explanation:

Given that,

Charge density of the plane $\sigma=7.65\times10^{−4}\ C/m^2$

Distance = 1.05 mm

We need to calculate the electric field due to plane of charge

Using formula of electric field

$E=\dfrac{\sigma}{2\epsilon}$

Put the value into the formula

$E=\dfrac{7.65\times10^{−4}}{2\times8.85\times10^{-12}}$

$E=4.322\times10^{7}\ N/C$

We need to calculate potential difference

Using formula of potential difference

$V=E\times r$

Put the value into the formula

$V=4.322\times10^{7}\times1.05\times10^{-3}$

$V=4.5381\times10^{4}\ Volt$

We need to calculate the work requires to be done to reach the surface of the plane

Using formula of work done

$W=qV$

Put the value into the formula

$W = 1.6\times10^{-19}\times4.5381\times10^{4}$

$W=7.26096\times10^{-15}\ J$

We need to calculate the velocity

Using work energy theorem

$W=\dfrac{1}{2}mv^2$

$v^2=\dfrac{2W}{m}$

$v=\sqrt{\dfrac{2\times7.26096\times10^{-15}}{1.67\times10^{-27}}}$

$v=2.94\times10^{6}\ m/s$

Hence, The velocity is $2.94\times10^{6}\ m/s$ .

What does it mean to control variables

olga55 [171]

Controlled variables are influences that could affect the outcome of an experiment, and so are purposely controlled so that they do not impact the experimental results.

What is the relationship between kinetic and potential energy in a roller coaster.

sukhopar [10]

Answer:

Kinetic energy is energy that an object has as a result of its motion. All moving objects possess kinetic energy, which is determined by the mass and speed of the object. Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released.
