Two masses are connected by a string. Mass A is on a flat roof and mass B is hanging over the edge of the roof. The mass on the roof is 15 kg and the hanging mass is 5 kg. The edge of the roof is 100 m above the ground. The two masses are initially at rest with the hanging mass 80 m above ground and the roof mass 50 m from the edge. There is no friction. (Allowed to use only work/energy no kinematics) after three seconds of motion the masses have moved 11 m. a) calculate the speed of the masses at this instant b) calculate tension in the rope c) at this instant the mass on the roof travels along a section with friction where u= .577. how far along the roof does this mass move before stopping (the masses are still connected).
Two point charges are placed on the x-axis. Charge Q1=+3 microC at x==-6cm and charge Q2=+3microC at x=+6cm. Find the magnitude and direction of the total electric field at point P
A particle of charge +e is initially at coordinate z = 20 nm on the dipole axis through an electric dipole, on the positive side of the dipole. (The origin of z is at the dipole center.) The particle is then moved along a circular path around the ..
