A negative charge -5Q is located at the origin. Take +x to the right and +y to up. Point P is at a displacement 6W from the origin and at angle of 20 degrees counter-clockwise from the plus y axis, i.e., up. What is the y component of the electric field at point P? Draw it out! O -5KQ/(36 W² cos² (20°)) O 5KQ/(36 W² sin² (20°)) 5KQ sin(20°)/(36 W²) 5KQ/(36 W² cos² (20°)) None of the other answers is correct. 5KQ cos(200)/(36 W²) O -5KQ/(36 W² sin² (20°)) -5KQ cos(20°)/(36 W²) -5KQ sin(20°)/(36 W²)
A charged ball has a negative charge of - 0.04 milli-coulombs is in an electric field of (0.51 -0.7 ĵ) mega- newtons/coulomb. The mass of the ball is 200 grams. What is the x component of the acceleration of the ball in m/s²? Neglect all other forces. Be careful with your factors of 10. Reminder: milli = 10-³ and mega = 106. You will need to be within 2% so keep 3 significant digits in your answer.
