Two point charges q1 and q2 are held in place 4.50 cm apart. Another point charge Q = -1.75 mC, of mass 5.00 g, is initially located 3.00 cm from both of these charges and released from rest. You observe that the initial acceleration of Q is 324 m>s2 upward, parallel to the line connecting the two point charges. Find q1 and q2.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

the independent variable, or the one that is intentionally manipulated is the speed.
