we are able to ignore the distance effect as the distance of a point is far away or much bigger than the distance than the distance between two charges of dipole
car protects in thunderstorm as car has metallic body which is like faraday cage and prevents us from hit by electric field from cloud to hit us and prevents lightning strike
london dispersion leads to intermolecular attraction as temporary dipole creates a electric field that is experienced by other molecules

Question 5 (3 points) A horizontal dipole has the positive charge located at (+x, 0) and the negative charge located at (-x,0) where x is a very small distance. If we are looking at a point directly above the dipole (0, 5 m), and see an electric field of 9,141,100 N/C, determine the dipole moment of the dipole. Your Answer: Answer units Question 6 (3 points) A horizontal dipole has the positive charge located at (+x, 0) and the negative...
An electric dipole is formed from two charges, ±q, spaced a distance s apart. The distance s is small compared to 10 cm. The dipole is at the origin, and the dipole moment p⃗ points in the y-direction. The electric field strength at the point P:(x,y)=(0cm,10cm) is 320 N/C 1. The two charges, ±q, are spaced a distance s apart. The dipole moment p⃗ is rotated 90∘ so it points in the +x-direction. What is the electric field E⃗ at the point P:(x,y)=(0cm,10cm) ? Give your...
What is the magnitude of the dipole moment for the two charges, q, spaced a distance s apart? Express your answer with the appropriate units. Review An electric dipole is formed from two charges, ±q, spaced a distance s apart. The distance s is small compared to 10 cm. The dipole is at the origin, and the dipole moment p points in the y- direction. The electric field strength at the point P : (x, y ,(0 cm, 10 cm)...
An electric field can induce an electric dipole in a neutral molecule (or atom) by pushing the positive and negative charges inside the molecule in opposite directions. The dipole moment of the induced dipole is directly proportional to the electric field at the molecule. That is, p⃗ =αE⃗ , where p⃗ is the induced dipole moment, α is called the polarizability of the molecule, and E⃗ is the electric field at the molecule. A stronger electric field at the molecule results in a...

8.Show that at points along the axis of a dipole (along the line joining the two charges), the electric field has magnitude 1 2p for rl, where r is the distance from a point to the center of the dipole. Indicate the direction in which E point. Note that there is an extra factor of two in the equation above, which differs from Eq. 21-12. Hint: Use binomial approximation.

Two parallel, metal plates with separation distance d = 1.00 cm carry charges of equal magnitude but opposite sign. The plates are oriented horizontally. Assume the electric field between the plates is uniform, and it has a magnitude of 1,920 N/C. A charged particle with mass 2.00 ✕ 10−16 kg and charge 1.11 ✕ 10−6 C is projected from the center of the bottom negative plate with an initial speed of 1.11 ✕ 105 m/s at an angle of 37.0°...

We are sometimes exposed to electric fields. To determine if there is a risk of overload, there is a rule of thumb that prevents sparks from switching if there is a field strength greater than 1kV per mm, ie 1MV / m. a) How big is the electrical field most between two conductors in a 230V wire (the peak voltage is 324V)? We assume that the distance between the conductors is 2mm. Reply with a rounded integer. Answer in [kV/m]...
