Question: A person weight 710 N lies in a hammock supported on either end by ropes that are at angles of 45 degree and 30 degree with the horizontal,
Part A: Find the tension in the ropes?
I want you to explain the physics in this question.
A small sphere with a mass of 0.002g and carrying a charge of 5*10^-8C hangs froma thread near a very large, charged conducting sheet. The charge density on the sheet is 2.5*10^-9C/m^2. Find the angle of the thread.
A beam of electrons traveling with speed 0.8 x10^(8) m/s passes through a slit of width 10^(-5) m. Because of the uncertainty in the lateral position of the beam, there will be an uncertainty in the transverse momentum as well.
