Calculate the magnitude of the electric field at one corner of a square 2.42 m on a side if the other three corners are occupied

Karolina [17]

Ans:

12500 N/C

Explanation:

Side of square, a = 2.42 m

q = 4.25 x 10^-6 C

The formula for the electric field is given by

$E = \frac{Kq}{r^2}$

where, K be the constant = 9 x 10^9 Nm^2/c^2 and r be the distance between the two charges

According to the diagram

BD = $\sqrt{2}\times a$

where, a be the side of the square

So, Electric field at B due to charge at A

$E_{A}=\frac{Kq}{a^2}$

$E_{A}=\frac{9\times10^{9}\times 4.25 \times 10^{-6}}{2.42^2}$

EA = 6531.32 N/C

Electric field at B due to charge at C

$E_{C}=\frac{Kq}{a^2}$

$E_{C}=\frac{9\times10^{9}\times 4.25 \times 10^{-6}}{2.42^2}$

Ec = 6531.32 N/C

Electric field at B due to charge at D

$E_{D}=\frac{Kq}{2a^2}$

$E_{D}=\frac{9\times10^{9}\times 4.25 \times 10^{-6}}{2\times 2.42^2}$

ED = 3265.66 N/C

Now resolve the components along X axis and Y axis

Ex = EA + ED Cos 45 = 6531.32 + 3265.66 x 0.707 = 8840.5 N/C

Ey = Ec + ED Sin 45 = 6531.32 + 3265.66 x 0.707 = 8840.5 N/C

The resultant electric field at B is given by

$E=\sqrt{E_{x}^{2}+E_{y}^{2}}$

$E=\sqrt{8840.5^{2}+8840.5^{2}}$

E = 12500 N/C

Difference between object distance and image distance within 4 points .(class 10)

Sergio039 [100]

The relationship between object distance, image distance, and focal length of a spherical mirror is given by

1/f=1/v+1/u

Where

f= focal length of a spherical mirror (distance between the pole and the principal focus of the mirror)

u= object distance (distance between pole and object)

v= image distance (the distance between pole and image)

If you swing a bucket of water fast enough in a vertical circle, at the highest point the water does not spill out. This happens

amm1812

Answer:

True

Explanation:

If we swing a bucket of water fast enough in a vertical circle the water does not spill out even at the top-most position of the bucket. This happens because the centrifugal force acting away from the center in a circular motion neutralizes or overcomes the gravitational force on the water particles.

<u>Centrifugal force is mathematically related as:</u>

$F=m.r.\omega^2$

where:

m = mass of the revolving body

r = radius of revolution

$\omega=$ angular velocity in radians per second

This force F acts in radially outward direction.

find out how was life like in ancient China by exploring the engineering and metal technology of Ancient China. Gather some poin

scZoUnD [109]

The grand canal was built to make easier the transportation of grains to the power center of north china.

<h3>How was the Grand Canal built?</h3>

The canal was built in order to connect the Yellow River in the north with the Yangtze River in the south. This canal is built for making easier the transportion of grain from the south to the centers of north China. The total length of the Grand Canal is 1,776 km.

So we can conclude that the grand canal was built to make easier the transportation of grains to the power center of north china.
