Two infinite plane sheets with uniform surface charge densities are placed parallel to each other with separation d. in the regi

kupik [55]

Answer:Uniform between the plates

Explanation:

Electric Field due to infinite sheet with uniform charge is given by

$E=\dfrac{\sigma }{\epsilon _0}$

Where $\sigma$ =charge density

$\epsilon _0$ =Space Permittivity

From the formula we can see that Electric field is independent of distance of the particle, so it is uniform between the plates .

Water flows through a multisectional pipe placed horizontally on the ground. The velocity is 3.0 m/s at the entrance and 2.1 m/s

Stolb23 [73]

Answer:

$P_1 - P_2 = 2295 pascal$

Explanation:

As we know by Bernoulli's principle

$P_1 + \frac{1}{2}\rho v_1^2 = P_2 + \frac{1}{2}\rho v_2^2$

$P_1 - P_2 = \frac{1}{2}\rho v_2^2 - \frac{1}{2} \rho v_1^2$

here we know that

$\rho = 1000 kg/m^3$

also we know that

$v_1 = 2.1 m/s$

$v_2 = 3 m/s$

now we have

$P_1 - P_2 = \frac{1}{2}(1000)(3.0^2 - 2.1^2)$

$P_1 - P_2 = 2295 pascal$
