a) Construct a free-body diagram for the ladder.
b) Determine the torque caused by each force in the diagram.
c) Add the torques to determine the net torque.
Please show all work for all 3 parts of the question.
Two 7.00 µC charged particles are located on the x axis. One is at x = 1.00 m, and the other is at x = -1.00 m. Determine the electric field on the y axis at y = 0.700 m
If the exospheric temperature is 1500 K and the hydrogen atom and helium atom densities at 500 km are 10^4 cm^3 and 10^6 cm^3 respectively,
