A ball is thrown up in the air from the ground with an initial speed of 25 m/s. It reaches its maximum height, and on its way down, gets stuck in between some tree branches at a height of 15 m. Calculate the total time of flight of the ball (in seconds) till it gets stuck in the branches.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

as technology advances, new experiments often expose problems in accepted theories. c
