1. Compute the force of attraction between

a +1.60 x 10 ^-19 C charge and a -2.09 x 10^-18 C charge if they are 4.01 x 10^-10 m apart.

2. Two ball bearings with opposite charges are 1.11 m apart on the floor on the floor. What are their charges if they are attracted to each other with a force of 5.11 N?

3. Compute the electric field experienced by a test charge q =+0.80μC from a source = +0.15μC in a vacuum when the test charge is places 0.20 m away from the other charge.

4. A.

E = 3.4 x 10^23 N/C

A = 2.3 x 10-2m²

Cos = 84⁰

B.

E= 8.2 x 10^5 N/C

A = 6.1 x 10^-7m²

Cos = 90⁰

The grade of steel is E250. Design a pair of equal angle section placed on each side of gusset plate. Draw schematic diagram showing Plan and Section

A pilot is required to fly directly from London, UK, to Rome, Italy.In order toarrive in Rome on time, the velocity of the plane relative to the ground must be 400 km/h [S43°E].If a wind is blowing with a velocity of 75 km/h [S], determine what the velocity of the plane relative to the air must be in order for the pilot to arrive in Rome on time.

An aircraft traveling with a velocity relative to the air of 320 km/h [S62°W] passes over Winnipeg.The wind velocity is 72 km/h [S].Determine the velocity of the plane relative to the ground.

A motor cycle is accelerated from rest to 60m/s in 16 seconds. If the engine force required to achieve this 1200N and effects due to friction are ignored, calculate the mass of the motor cycle.

Two point charges are placed as follows: charge q_{1} = - 1.50nC is at y = 6.00 m and charge q_{2} = 3.20nC is at the origin. What is the total force (magnitude and direction) exerted by these two charges on a negative point charge q_{3} = - 5.00nC located at (2.00 m, -4.00 m)?
