Two charges are located in the x–y plane. if q1 = -2.90 nc and is located at x = 0.00 m, y = 0.840 m and the second charge has magnitude of q2 = 5.00 nc and is located at x = 1.00 m, y = 0.800 m, calculate the x and y components, ex and ey, of the electric field, , in component form at the origin, (0,0). the coulomb force constant is 1/(4π ε0) = 8.99 × 109 n·m2/c2.

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
