- A proton is shot directly upward toward the sky from the east coast of the US. What does itssubsequent path look like if we assume it's done in vacuum so that the electron won't impact airmolecules?Calculate the value of an electric field at a point 5 m away from two positive electric charges of 69.9 µC and 20 μC that are located 10 m apart in vacuum. Provide your answer in Sl units. Answer: Choose...A thread is tied to a charged 3-gram pith ball and attached to the ceiling at a location of a uniform electric field with an intensity of 500 N/C. The pith ball experiences an electric force which causes it to deflect from an otherwise vertical alignment by an angle of 12.6° from the vertical. Determine the vertical and horizontal components of the tension force of the thread. (Hint: Draw a free-body diagram.) A) vertical .0294 N, horizontal -.0066 N B) vertical .0066 N, horizontal -.0294 N

(d) Directed southeastward? The answers are a) west b) zero deflection c) up d) down. Can you explain#2: A 0.050-kg cart has a spherical dome that is charged to +1.0 x 10- C. The cart is at the top of a 2.0-m-long inclined plane that makes a 30° angle with the horizontal. The cart and the plane are placed in an upward-pointing vertical uniform 4000-N/C E field. How long will it take the cart to reach the bottom of the plane? What assumptions did you make?1) An initially non-charged gold leaf inside an electroscope has a total dimension of 2 [cm] x 4[cm]. It is folded in half to have two equal squares of 2 [cm] x 2 [cm] on either side.1a) A charged probe of +5*10^(-6) [C] is brought near the tip of the electroscope but does nottouch. What effect do you predict will happen to the gold leaves and why? 1b) The same charged probe now makes contact to the electroscope and it's net charge isreduced to +2.5*10^(-6) [C] and the electroscope is removed. Explain what had happened andwhat is the surface charge density of each of the squares of the gold leaf? 1c) If the gold leaf squares are separated by an angle of 90 degrees, what is the magnitude ofthe electric force per area between the centers of the squares? got part B I got -6.25*10^-3 and for part C I got -281.25 N/m^2 is this correct?
