Question1

Find out a magnitude and direction of the electric field this arrangement of charges produces at point, that lies 6.00 from the - charge measured perpendicular to the line connecting the three charges. Suppose that = 4.80 and = 2.35.

Question2

A square steel plate is 13.0cm on a side and 0.600cm thick. Imagine that plate is oriented with the square faces horizontal to ground. Find out the shear strain that results if a force of magnitude 5.00×105N is applied to the top square face of the plate, parallel to the side, and a force of equal magnitude is applied in opposite direction to the bottom face of the plate. Find out the displacement Deltax in centimeters.

Question3

A m1 = 13.5 kg object and a m2 = 11.5 kg object are suspended, joined by a cord that passes over a pulley with a radius of 10.0 cm and a mass of 3.00 kg .The cord has a insignificant mass and does not slip on pulley. The pulley rotates on its axis without friction. The objects start from rest 3.00 m apart. Treating the pulley as a uniform disk, establish speeds of the two objects as they pass each other.
