The relationship between the electric force F (e) and the gravitational force F (g) (or 1. weight) between two electrons. Two equal and equally charged spheres of 0.1 g of mass each are suspended from the same point by threads of 13 cm in length. Due to the repulsion between both, the spheres are separated 10 cm as seen in the graphic representation. Find the load of 2. each of them. Calculate the number of electrons that add an electric...

Please do both problems and explain steps Chapter 18, Problem 10 2 Your answer is partially correct. Try again. Two tiny conducting spheres are identical and carry charges of -16.2HC and +61.0fHC. They are separated by a distance of 3.74 cm. (a) What is the magnitude of the force that each sphere experiences? (b) The spheres are brought into contact and then separated to a distance of 3.74 cm. Determine the magnitude of the force that each sphere now experiences...
Chapter 2, Problem 2/103 Express the 5.1-kN force F as a vector in terms of the unit vectors i, j, and k. Determine the scalar projections of F onto the x-axis and onto the line OA. 2 F-5.1 kNT 64° Answers: k) kN kN FOA kN
Question 1 options: Determine the moment of force F about an axis extending between A and C. Express the result as a Cartesian vector. Use F = {5i + 10j - 4k} kN, L1 = 5 m, L2 = 4 m, and L3 = 3 m for your calculations. Your answer: x-component of the resultant moment in kNm (round the result to 1 decimal place): y-component of the resultant moment in kNm (round the result to 1 decimal place): z-component...
