Repulsive. I was unclear, but if the question is whether I took it into account when adding the horizontal components, I did. -->.00025 + (-1.3824x10^-4)

Homework Statement Consider the three charges in the figure below, in which d = 4.7 cm, q = 11 nC, and the positive x-axis points to the right. What is the force Fvec on the 5 nC charge? Give your answer as a magnitude and a direction. Homework Equations F= (K*Q*q)/r^2 The Attempt...

Well to add vectors you just add them keeping in mind direction, and in this case both sides of the triangle would have the same vector. Wait, do you have to find the x and y components of the vector, and use those?

Homework Statement Consider the triangle of charges diagrammed below, for which d = 5 cm, q = 2 nC, and the +x-axis points to the right. What is the force Fvec on the 1 nC charge? Give your answer as a magnitude and a direction.Homework Equations F=K(q)(Q)/r^2 The Attempt at a Solution I...

Hi. I am a little stuck and I would appreciate some help. What is the acceleration due to gravity of the sun at the distance of 1.6 X 10^11 m? The asteroid revolves around the sun in 398 Earth days. 2. Homework Equations : F= (m*V^2)/r3. The Attempt at a Solution : First I found the...

The figure below shows a block of mass m resting on a 20° slope. The block has coefficients of friction µs = 0.74 and µk = 0.52 with the surface. It is connected via a massless string over a massless, frictionless pulley to a hanging block of mass 2.0 kg. (a) What is the minimum mass m that...

Alright, I redid my algebra and that is where the problem was...I am rather embarrassed! Thank you for your help PhanthomJay.

Hello everyone, I would appreciate some help with this problem: The coefficient of kinetic friction between the 1.2 kg block in the figure below and the table is 0.38. What is the acceleration of the 1.2 kg block? Homework Equations F=M*A Fk = μk * N The Attempt at a Solution I created...
