Multiple-concept example 7 discusses how problems like this one can be solved. a 6.00-μc charge is moving with a speed of 8.70 x 104 m/s parallel to a very long, straight wire. the wire is 6.30 cm from the charge and carries a current of 86.0 a. find the magnitude of the force on the charge.

Aclarinetist, setting out for a performance, grabs his 3.350 kg clarinet case (including the clarinet) from the top of the piano and carries it through the air with an upward force of 24.65 n. find the case's vertical acceleration. indicate an upward acceleration as positive and a downward one as negative.
