Two 10-cm-diameter charged rings face each other, 25.0 cm apart. Both rings are charged too + 50.0 nC . What is the electric fie
Kamila [148]

Answer:6773.54 V/m

Explanation:

Given data

Distance between two rings(x)=25cm

Charge on each ring(Q)=50\times 10^{-9} C

diameter of ring(d)=10 cm

Now Electric field strength at distance x from ring=\frac{kxQ}{\left ( x^{2}+r^{2}\right )^{1.5}}

Where K=coulomb's constant=\frac{1}{4\pi \epsilon_0}=8.98\times 10^{9]

Now electric field strength at midpoint between two rings is zero

because one is pointing towards positive x direction and other in negative z direction.

but electric field strength at center of ring  due to other ring is given by

\left ( E\right )_{ring}=\frac{kxQ}{\left ( x^2+r^{2}\right )^{1.5}}

\left ( E\right )_{ring}=\frac{8.98\times 10^{9}\times 0.25\times 50\times 10{-9}}\left ( 0.25^2+0.05^{2}\right )}^{1.5}}

\left ( E\right )_{ring}=6773.54 V/m

an empty bottle has a mass of 24,25 grams and 86,55 grams completely full-filled with water. Then, water in the bottle is emptie
ladessa [460]
The density of a substance is the quotient we obtain when we divide its mass by the volume. The density is,
                          density = mass / volume
The mass of carbon tetrachloride is given to be 123.95 grams and that the volume is obtained by subtracting final weight of the completely full-filled with water bottle with the initial weight.
                              86.55 - 24.25 = 62.3 grams
Since the density of water is 1 grams/ cc. Then, the volume of the bottle is also 62.3 cc. The density is therefore,
                       density = 123.95 grams/ 62.3 cc = 1.99 g/cc
