Use Coulomb’s Law to determine the magnitude and direction of the electric field EB at
point B in the diagram due to the two positive charges (Q = 7.0 μC). If a proton is located
at point B, calculate the magnitude and direction of the force F acting on the proton.

Best ResponseYou've already chosen the best response.1E1 has the same direction as r1 E2 has the same direction as r2 find the magnitudes of each field in terms of Q find the 'x' and 'y' components of each field add the 'y' components; add the x components : those sums are the components of the net field

Best ResponseYou've already chosen the best response.1direction of E1 : angle is 45 so E1x = ((9E9*7E6)/.005m) *cos(45) E1y =((9E9*7E6)/.005m) *sin(45) (edited: now with more parentheses!!_

Best ResponseYou've already chosen the best response.0@Algebraic! yep its clear on how to get E2 but the question also want the force F acting on the proton also after getting the x and y components of E1 and E 2 how will it be added

Best ResponseYou've already chosen the best response.1yeah once you find the net field at a point, the force on a particle at that point is just qE, where q is the charge of the particle (the charge of a proton in this case: +e) "also after getting the x and y components of E1 and E 2 how will it be added" just add them! add the x comp of E1 and the x comp of E2, that's the x comp of the net field... repeat for y comp to find the magnitude of the net field, use sqrt( (x comp)^2 + (y comp)^2 ) to find the direction of the net field, use arctan( x comp / y comp)
