A disk of radius R = 9.54 cm, is centered at the origin and lies along the y–z plane. The disk has a surface charge density σ

= 4.07 × 10-6 C/m2. Evaluate the electric field produced by this disk along the x axis at point P = (1.01 m, 0.00 m). The Coulomb force constant k = 1/(4π ε0) = 8.99 × 109 N·m2/C2.

Answer:

Electric field by charged disk is given as

E = (Charge Density/2u0)*[1 - (z/sqrt(z^2 - R^2))]

R = 9.54cm = 0.0954m, z = 1.01m, Charge density = 4.07 x 10^-6C/m2, e0 = 8.85 x 10^-12F/m.

Substituting all the values in to equation,

E = (2.299 x 10^5) x (8.931 x 10^-3)

E = 2.053 x 10^3N/C

Two conducting spheres are mounted on insulating rods. They both carry some initial electric charge, and are far from any other
natka813 [3]

The question is incomplete. The complete question is :

Two conducting spheres are mounted on insulating rods. They both carry some initial electric charge, and are far from any other charge. Their charges are measured. Then, the spheres are allowed to briefly touch, and the charge in one of them (sphere A) is measured again. These are the measured values:

 a). Before contact:

Sphere A = 4.8 nC

Sphere B = 0 nC

What is the charge on sphere B after contact, in nC?

b). Before contact:

Sphere A = 2.9 nC

Sphere B = -4.4 nC

What is the charge on sphere B after contact, in nC?

Solution :

It is given that there are two spheres that are conducting and are mounted on an insulating rods which carry a initial charge and they are briefly touched and then one of the charge is measured.

Here the charge becomes divided when  both the spheres are connected and then removed.

a). charge after they are charged

   $Q = \frac{q_1+q_2}{2}$

    $Q = \frac{4.8+0}{2}$

      = 2.4 nC

b). The charge is

    $Q = \frac{q_1-q_2}{2}$

    $Q = \frac{2.9-4.4}{2}$

      = -0.75 nC

In what direction would you head from New York state to find warmer temperatures
Anni [7]
Head south. If you traveled west, it would gradually get warmer because the Pacific Coast is warmer than the Atlantic. But the quickest change would be if you traveled south to North Carolina and there you would experience warmer temperatures.
The climate would still be humid as it's still near the coast, but since it's closer to the equator, it would be warmer.
