Two charged bees land simultaneously on flowers that are separated by a finite distance. For a few moments, the charged bees rest on the flowers. The charged bees both generate an electric field, and while the charged bees are resting on the flowers, the net electric field at some distance between them is zero. (a) Do the bees have the same or opposite signs of charge? O Same - the electric fields point in opposite directions and therefore cancel at some midpoint. O Same - the electric fields multiply together to equal zero. O Opposite the electric fields point in the same direction summing to zero. O Opposite the net electric field due to the two bees points in a direction perpendicular to the direction from one bee to the other. (b) Suppose the net electric field is zero at a distance that is closer to bee 1. Does bee 1 have a magnitude of charge greater than or less than that of bee 2? O greater than O less than

#11) The figure below shows an electron passing between two charged metal plates that create a 100 N/C vertical electric field perpendicular to the electron’s original horizontal velocity. (These can be used to change the electron’s direction, such as in an oscilloscope.) The initial speed of the electron is 3.00 x 106 m/s, and the horizontal distance it travels in the uniform field is 4.00 cm. a) What is its vertical deflection? b) What is the vertical component of its final velocity? c) At what angle does it exit? Neglect any edge effects. (Please answer C)

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?
