Question

Problem 6 [7] You are tasked with analyzing an old set of data. Unfortunately, a portion of the data has become corrupt and can only access a portion of the data. You read that the system contains 2 charged particles: Particle A: Located at the origin with a - +900 nC. Particle B: Located at {missing data with a charge of qy = -500 nC. You are given that the net force on particle A is F = (12 i - 7)) N. Your task: What is the position of particle B? Problem 7 [10] Twe point charges are separated by a distance of 10.0 cm on the x-axis. One has a charge of -25 uC and the other +50 u. a) Determine the direction and magnitude of the electric field at a point P between the two charges that is 2.0 cm from the negative charge. b) If an electron (mass = 9.11 X10-31 kg) is placed at rest at P and then released, what will be its initial acceleration (direction and magnitude)? Problem 8 [15] 4000 grams of water is placed in a vacuum chamber with dimensions of 2m by 2m by 2m at T-40°C. What is the final (ie, equilibrium) pressure inside the system? Assume the water vapor can be modeled as a ideal gas.
