Q An infinitely long line of charge has a linear charge density of 6.50*10^-12 C/m. a proton is a distance of 17.5 cm from the line and moving directly toward the line with a speed of 2900 m/s. How close does the proton get to the line charge? I am lost and do not know how to approach the...

Two protons are aimed directly toward each other by a cyclotron accelerator with speeds of 1650 km/s,measured relative to the earth. find the maximum force that these protons will exert on each other. KE_i + U_i = KE_f + U_f ;where U_i=0 and KE_f=0,so KE_i=U_f if r=...

is r=((q^2/4*pi*epsilon_0)(1/K_i)

not clear on concept Q Two protons are aimed directly toward each other by a cyclotron accelerator with speeds of 1650 km/s, measured relative to the earth. find the maximum electrical force that these protons will exert on each other? K_a + -U_a= K_b + U_b and K_a=0, U_b=0 -U_a=K_b K_b=...

#! A flat sheet is in the shape of a rectangle with sides of length 0.400m and0.600m. the sheet is immersed in a uniform electric field 71.0 N/C that is directed at 20 deg. from the plane of the sheet. Find the magnitude of the electric flux through the sheet? A = L*W= 0.600m*.400. E = 71 N/C...

need help to set up problem? partA: suppose all the electrons in a quantity of carbon atoms with a mass m were located at the North Pole of the Earth and all the protons at the south pole. what would be the total force of attraction exerted on each grup of charges by the other? The atomic...
