*can you help with  4c *this is not and will not be graded On a typical clear day, the atmospheric electric field points downward and has a magnitude of roughly 100 N/C. 4a. How does the electric field and the (positive) charge acquired affect the bee?  A.  As the bee collects pollen (and positive charge), its effective weight increases. B.  As the bee collects pollen (and positive charge), its effective weight decreases. 4b.What is the (gravitational) weight of an 0.1 gram Bumblebee? 4c.After the bee has acquired a charge of 23 pC, what is the magnitude of the electric force that adds/subtracts to its effective weight?

Item 9 A point charge with charge q1 = 2.80 μC is held stationary at the origin. A second point charge with charge q2 = -4.70 μC moves from the point (0.125 m, 0) to the point (0.250 m, 0.270 m ). Part A How much work is done by the electrostatic force on the moving point charge?

The three q1=q2=q3 = 14 μC charges came into the arrangement shown below from very far apart. q1 is located at (0.00, 5.2) cm, q2 is located at (0.00, -5.2) cm and q3 located at (13.26, 0.00) cm a) How much work must be done to move the three charges into the arrangement shown if they started very far apart?  b) What is the work if the particle on the right, q3, with mass 49.5 g, is released from rest and allowed to move freely to point P, twice 13.26 distance, figure below? c) How fast, in m/s, is q3 moving when it has moved to point P, twice 13.26 distance? To continue, please submit the result of part (c) in units of m/s.   Round your answer to 0 decimal places.

10 nC В A -5 nC You wish to place a charge at A, which when released will move away from the two charges shown, and then determine the speed of the charge when it gets an infinite distance away from the two charges. The rectangle is 18.4 cm high and 21.9 cm wide. In order for the charge placed at A to move to infinity, you must use an electron O a proton When released, approximately which direction will the charge initially accelerate? Image an analog clock face placed at A with 12 o'clock upward. toward 7 o'clock How fast will the charge be moving when it gets an infinite distance from the two charges? X m/s

Ē 4περτ2 This problem checks your understanding of the term in the equation for the electric field due to a point charge, Consider a charged particle at a point S whose coordinates are (10 m, 10 m, 7 m). We would like to find the electric field vector at a point P whose coordinates are (4 m, 5 m, 5 m). The term is the distance between point S and point P. What is its value, in meters? 1 Q ↑
