The electric field in a region is uniform (constant in space) and given by E-( 148.0 1 -110.03)N/C. An additional charge 10.4 nC

Alexandra [31]

Answer:

$-1.144\ \mu C$

Explanation:

Given:

$\vec{E}$ = uniform electric field in the space = $(148.0\ \hat{i}-110.0\ \hat{j})\ N/C$

Q = Charge placed in the region = $10.4 nC\ = 1.04\times 10^{-8}\ nC$

Assume:

$\vec{F}$ = Electric force on the charge due to electric field

We know that the electric field is the electric force applied on a unit positive charge i.e.,

$\vec{E}=\dfrac{\vec{F}}{Q}$

This means the electric force applied on this additional charge placed in the field is given by:

$\vec{F}=Q\vec{E}\\\Rightarrow \vec{F} = 1.04\times 10^{-8}\ n C\times (148.0\ \hat{i}-110.0\ \hat{j})\ N/C\\\Rightarrow \vec{F} = (1.539\ \hat{i}-1.144\ \hat{j})\ \mu N\\$

From the above expression of force, we have the following y-component of force on this additional charge.

$F_y = -1.144\ \mu N$

Hence, the y-component of the electric force on the this charge is $-1.144\ \mu N$ .

A thunderstorm starts to form when water evaporates to form clouds. Which of the following best explains why thunderstorms usual

Morgarella [4.7K]

Thunderstorms might form on warm days simply because heat is what causes evaporation, causing rain. Thunderstorms also form when the atmosphere is unstable! Meaning the hot air is above the cold air, evaporation occurs, it rains, and then rapid expansion of heat in the air caused by lighting causes thunder.

Stacey runs around a 400 meter track 2 times in 5 minutes. How does her displacement differ from her distance? *

liq [111]

Answer:

Distance is 800 m and Displacement is 0 m

Explanation:

Total Distance

= 400(2)

= 800 m

Total Displacement

= 0 m since she returns to the same spot
