Along solenoid with 1.65 103 turns per meter and radius 2.00 cm carries an oscillating current i = 6.00 sin 90πt, where i is in amperes and t is in seconds. what is the electric field induced at a radius r = 1.00 cm from the axis of the solenoid? (use the following as necessary: t. let e be measured in millivolts/meter and t be measured in seconds.)

The  electric field  is

Explanation:

Given that,

Radius = 2.00 cm

Number of turns per unit length

Current

We need to calculate the induced emf

Where, n = number of turns per unit length

A = area of cross section

=rate of current

Formula of electric field is defined as,

Where, r = radius

Put the value of emf in equation (I)

....(II)

We need to calculate the rate of current

....(III)

On differentiating equation (III)

Now, put the value of rate of current in equation (II)

Hence, The  electric field  is

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

it is the second option.
