Avery long wire carries a uniform linear charge density of 6 nc/m. what is the electric field strength 10 m from the center of the wire at a point on the wire's perpendicular bisector? (ε 0 = 8.85 × 10-12 c2/n · m2)

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
