Two layers of plastic food wrap (which can be very highly electrically charged via static electricity),...
Some cell membranes in the human body have a layer of negative charge on the inside surface and a layer of positive charge of equal magnitude on the outside surface. Suppose that the charge density on either surface is ± 0.50×10−3 C/m2, the cell membrane is 5.00 nm thick, and the cell membrane is made up of tissue with a dielectric constant of 5.40. A) Find the magnitude of E in the membrane between the two layers of charge. E=?...
Bl A co-axial cable can be treated as two straight cylindrical layers with length of h -6 cm, radii of a lcm and b 4 cm, that is filled with air. Let there be a charge ( +12 pC) on the inner layer and - -12 pC) on the outer layer (as shown in Fig. Bla). Assume each layer has negligible thickness. -Q bt Fig. Bla Fig. Blb (1) Find the electric field intensity E (p) and potential difference in...
Tutorial 9: Electricity I (week 10) 1) A typical thunderstorm can be regarded as comprising two charges of +40 C and -40 C, separated in air by a distance of 5 km Calculate the magnitude of the force between the charges 2) Four charges are arranged at the corners of a square with sides length, L, as shown Q: 4 mC, q = 2 mC and L = 10 cm a) Find the magnitude of the .Q net force on...
