Given a configuration of three charged particles such that q1= 5.30 nC at (1.50 m, 0.0 m), q2= 9.20 n C at (0.00 m, 2.00 m) and q3= -2.40 nC at the origin
A 0.410 kg pendulum bob passes through the lowest part of its path at a speed of 3.13 m/s. What is the tension in the pendulum cable at this point if the pendulum is 76.2 cm long.
There is a uniform magnetic field present, given by B=0.003 i + 0.004 j + 0.002 k, where i,j,k are the unit vectors along the cartesian coordinate axes in units of Tesla. Compute the y-component of the magnetic force acting on a segment of wire of..
A steel beam is suspended completely under water by a cable that is attached to one end of the beam, so it hangs perpendicularly. Another identical beam is also suspended completely under water, but by a cable that is attached to the center of the be..
