Consider a collection of charges in a given region and suppose all other charges are distant and have a negligible effect. Furth
AlladinOne [14]

Answer:

E. Some charges in the region are positive, and some are negative.

Explanation:

Electric potential is given as;

V = \frac{W}{Q}

where;

W is the work done in moving a charge between two points which have a difference in potential

Q is quantity of charge in the given region

If the electric potential at a given point in the region is zero, then sum of the charges in the given region must be equal to zero. For the charges to sum to zero, some will be positive while some will be negative,.

Therefore, the correct statement in the given options is "E"

E. Some charges in the region are positive, and some are negative.

If a point charge is located at the center of a cylinder and the electric flux leaving one end of the cylinder is 20% of the tot
zheka24 [161]

The portion of the flux leaves the curved surface of the cylinder is 60%.

<h3 /><h3>What are electrons?</h3>

The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.

If a point charge is located at the center of a cylinder and the electric flux leaving one end of the cylinder is 20% of the total flux leaving the cylinder.

If 20% of the flux leave from one end, then another 20% will leave from another end.

So, the net flux through curved surface is

100 -20 -20 = 60%

Thus, the total flux  leaves the curved surface of the cylinder is 60%

Two objects each with a mass of 5x10^15 kg have a gravitational
kipiarov [429]

Answer:

Distance, r = 700.31 m

Explanation:

Mass of two objects, m_1=m_2=5\times 10^{15}\ kg

Force between the objects , F=3.4\times 10^{15}\ N

We need to find the distance between the two objects. The force of gravitational between two objects is given by :

F=G\dfrac{m_1m_2}{r^2}\\\\r=\sqrt{\dfrac{Gm_1m_2}{F}} \\\\r=\sqrt{\dfrac{6.67\times 10^{-11}\times (5\times 10^{15})^2}{3.4\times 10^{15}}}\\\\=700.31\ m

So, the distance between the objects is 700.31 m.
