= Question 13 Two horizontal forces, F1 = 35 N east and F2 = 80 N west, as well as two vertical forces, F3 = 12 N south and F4 = 23 N south act at a fixed point. = = 13.1 Draw a representation of the forces on the Cartesian plane. 13.2 Determine the total horizontal force Rx and the total vertical force Ry acting at the point and represent it on the Cartesian plane. 13.3 Determine the magnitude and direction of the resultant force R. show your drawing

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.
