Three charged particles are placed at each of three corners of an equilateral triangle whose sides are of length 3.7 cm. Two of the particles have a negative charge: q1 = -8.3 nC and q2 = -16.6 nC. The remaining particle has a positive charge, q3 = 8.0 nC. What is the net electric force acting on particle 3 due to particle 1 and particle 2? Find the net force EF3 acting on particle 3 due to the presence of the other two particles. Report you answer as a magnitude EF3 and a direction 0 measured from the positive x axis.

Write Newton's laws for a static system (1) EF, = mg sin 0 – µ̟n = 0 in component form. The gravity force has two components. (2) EF, = n - mg cos 0 = 0 Rearrange Equation (2) to get an n = mg cos e expression for the normal force n. Substitute the expression for n into EF, = mg sin 0 – µ̟mgcos 0 = 0 → tan 0 =µ, Equation (1) and solve for tan 0. Apply the inverse tangent function to tan 0 = 0.350 → 0 = tan 1 (0.350) = 19.3° get the answer. LEARN MORE REMARKS It's interesting that the final result depends only on the coefficient of static friction. Notice also how similar Equations (1) and (2) are to the equations developed in previous problems. Recognizing such patterns is key to solving problems successfully. QUESTION A larger static friction constant would result in a: (Select all that apply.) O larger component of normal force at the maximum angle. O larger component of gravitational force along the ramp at the maximum angle. smaller component of gravitational force along the ramp…

please help answer, Im not sure what im doing wrong

Crates A and B have equal mass. Crate A is at rest on an incline that makes and angle of theta = 22.22 degrees horizontal, while crate B is at rest on a horizontal surface.   Write an expression for the ratio fo the normal forces, A to B in terms of theta?
