Let the distance form origin of the point on x-axis be x.

then (-k*2*q/x)+(k*q/(2R-x))=0

solving for x,

we get x=4R/3.

so, the curve is a sphere with center at (4R/3,0,0)

radius=2R-4R/3=2R/3.

Can sound travel through space? Why or why not?
DiKsa [7]

Answer:

I think sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.

An object with charge -4.0μC is placed between a positively charged object to the
elena-s [515]

The net force on the -4.0μC object as a result of this net field will be -10.4 N.

<h3>What is the charge?</h3>

The matter has an electric charge when it is exposed to an electromagnetic field is known as a charge.

The electric field intensity is found as the force per unit charge.

Electric field intensity on the positive charge:

\rm E_1 = \frac{F_1}{Q} \\\\\ \rm   1.2 N/C = \frac{F_1}{ -4.0 \mu C} \\\\ F_1 =   - 4.8 \ N

Electric field intensity on the negative charge:

\rm E_2 = \frac{F_2}{Q} \\\\\ \rm   1.4 \ N/C = \frac{F_1}{ -4.0 \mu C} \\\\ F_2 =  - 5.6 \ N

The net charge is the algebraic sum of the two charges;

\rm F_{net}=F_1+F_2 \\\\ F_{net}= -4.8 -5.6 \\\\ F_{net}=-10.4 \ N

Hence, as a result of this net field, the net force on the -4.0C object will be -10.4 N.
