You are trying to find out how high you haveto pitch a water balloon in order for it to burstwhen it hits the ground. You discover thatthe balloon bursts when you have pitched itto a height of 11 m. With what velocity did the balloon hitthe ground? The acceleration of gravity is9.8 m/s2. The positive direction is up, so thevelocity when it hits is negative. Answer in units of m/s.

A-4.60 μc charge is moving at a constant speed of 6.80×105 m/s in the +x−direction relative to a reference frame. at the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points.
