Acharge of +3.1 × 10-16 coulombs is moved between two points, resulting in a potential difference of +15 volts. what is the magnitude of the work done on that charge?

2.3 × 10-15 joules

4.7 × 10-15 joules

3.1 × 10-15 joules

9.2 × 10-15 joules

Work done,

Explanation:

It is given that,

Magnitude of charge,

Potential difference between two points,

We have to find the magnitude of work done on that charge. The relationship between the work done and the potential difference is given by :

or

Hence, the magnitude of work done on the charge is

your answer is yx

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.
