(c) Two infinite, nonconducting sheets of charge are parallel to each other, as shown in Figure 2. The sheet on the left has a uniform surface charge density a, and the one on the right has a uniform charge density -o. Calculate the electric field at points (i) Region 1: to the left of the two sheets, (ii) Region 2: in between of the two sheets, and (iii) Region 3: to the right of the two sheets. Find the field in all 3 regions if both sheets have positive uniform surface charge of value o. ( Figure 2

how do you solve for t in tcos0

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
