Please help with #4 and 5 will rate thank you! ) wnat is the magnitude and sign of the charge a 190 lb human being would have to have in order for the electric force to just overcome her weight? (b) What is the magnitude of th people separated by 100 m and each possessing the charge calculated in part (a s the force attractive or repulsive? (Hint: approximate each individual as a particle.) 4. A 240 g cup of...
A charge of 20.0-μC is held fixed at the origin. A -5.0-μC charge with a mass of 10.0 g is launched (outwards) from the position (1.0 m, 1.0 m) at a speed of 12.0 m/s. (a) At what distance from the origin will its speed be reduced to 6.0 m/s? (b) Will it ever halt? If yes, at what distance will it halt? Three point charges are located at the corners of an equilateral triangle, whose side l = 0.5...
A 4.5 μC point charge with a mass of 0.075 g is released from rest in a uniform electric field. a) If the electric field is 680 N/C, what is the acceleration of the charge? b) How long does it take the charge to go 25 m? c) What is the speed of the charge at that time? Please hand write out the answer and the work that goes along with it

A projectile is launched from the ground at 30 degrees from te horizontal at 45 m/s. A target is placed 30 m horizontally from the starting point at 8 m above the ground. Is the projectile going to hit the target? if not by what vertical distance is it missing the target? Is the projectile moving upward or downward at that instance?
