2 Blocks 1 and 2 rest on rough surfaces with coefficient of frictions ¢1 and ¢2 respectively. The blocks
are connected by a cable that runs over a smooth pulley and are in equilibrium as shown below with the following values.
W2 = 50N
thetha 1 = 30 degrees
thetha 2= 40 degrees
¢1= 0.3
¢2= 0.25
a. If Block 2 is on the verge of sliding down the plane, what is the minimum weight W1, required for equilibrium?
b. If Block 2 is on the verge of sliding up the plane, what is the minimum weight W1, required for equilibrium
? Do not consider overturning.

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).
