The charges and coordinates of two charged particles held fixed in the xy plane are: q1=6.00 ?C, x1=6.700 cm, y1=4.600 cm, and q2=8.90 ?C, x2=1.039 cm, y2=11.467 cm,
Find the a) magnitude and
b) direction of the electrostatic force on q2?
What are the c) x and
d) y coordinates of a third charge q3=8.60 ?C, if the net electrostatic force on q2 is zero?
Assuming that he starts from rest when the rope is horizontal, find out the tensions in the rope that are required to make him follow his circular path at each of the following points.
Sketch a free-body diagram of the plank. How far can a painter of mass 70.0 kg walk on the overhanging part of the plank before it tips.
what is the rate of heat transfer from the plate to the air? If the free stream velocity if the air is doubled and the pressure are increased to 10 atm, what is the rate of heat transfer.
A force F = 200i - 400j + FZ k N, is acting through point A(0,0,0) m. If F creates a moment component of -3000 Nm in the direction of a line passing from point B (2,4,5) m to point C(-3,6,8) m
Find out the magnitude of the friction force acting on the case. Laser light with a wavelength = 680 illuminates a pair of slits at normal incidence. What slit separation would produce first-order maxima at angles of 40 from the incident direction.
Light of wavelength 450 nm falls on the 0.48 mm wide slit and forms a diffraction pattern on a screen 1.1 m away.
A vessel whose walls are thermally insulated contains 2.00 of water and 0.550 of ice, all at a temperature of 0.0. The outlet of a tube leading from a boiler in which water is boiling at atmospheric pressure is inserted into the water.
How much of the rope must be pulled. Find the magnitude of the magnetic field at the point x = 0, y = 0.7 m, z = 0.
Estimate the wavelength of the light.
