A particle with charge +6.70 nC is in a uniform electric field directed to the left. Another force, in addition to the electric
mina [271]

Answer:

a) 4.6*10^{-5} J

b) 6133.33 J/C

c) 94358.9 C

Explanation:

(a) We have that the change in the kinetic energy equals the net work over the charge. Hence we have

\Delta E_K=W-W_E

where Ek is the kinetic energy, W is the work of the external force and WE is the work done by the electric field. By replacing we obtain:

W_E=W-\Delta E_k=7.60*10^{-5}J-3*10^{-5}J=4.6*10^{-5}J

(b) The potential difference is computed by using:

\Delta V=\frac{W_E}{q}=\frac{4.6*10^{-5}J}{7.5*10^{-9}C}=6133.33\frac{J}{C}

(c) With the work done by the electric force we can calculate the Electric field. By using the following formula we obtain:

W_E=qEd\\\\E=\frac{W_E}{qd}=\frac{4.6*10^{-5}J}{(7.5*10^{-9}C)(6.50*10^{-2}m)}=94358.9\frac{N}{C}

where we have used d=6.5cm=6.5*10^-9m and q=7.5nC=7.5*10^-9C

hope this helps!!

The gravitational force experienced by Earth due to the Moon is ________ the gravitational force experienced by the Moon due to
Vsevolod [243]

The gravitational force experienced by Earth due to the Moon is <u>equal to </u>the gravitational force experienced by the Moon due to Earth.

<u>Explanation</u>:

The force that attracts any two objects/bodies with mass towards each other is defined as gravitational force. Generally the gravitational force is attractive, as it always pulls the masses together and never pushes them apart.

The gravitational force can be calculated effectively using the following formula: F=GMmr^2  

where “G” is the gravitational constant.

Though gravity has the ability to pull the masses together, it is the weakest force in the nature.

The mass of the Earth and moon varies, but still the gravitational force felt by the Earth and Moon are alike.

Digiron [165]

Answer:

The answer is B- it decreases from 40 J to 37 J.

Explanation:

Because as you see it was at 8 then it went down 3 just like how it started at 40 and went down 3 to 37.
