Question

in the figure the length of wire AC is :(take BC=60ft)​

Answer 1

Answer:

Diagram ?

Step-by-step explanation:

in the figure where is the diagram please send me the diagram.

Answer 2

Answer:

Let the length of AB and BC is P

And

Radius of AB is 2r

Radius of BC is r

R

AB

=

π(2r)

2

ρP

=

4πr

2

ρP

And

R

BC

=

πr

2

ρP

Therefore

R

AB

=

Potential across AB

V

AB

=E[

E

Potential across BC

V

BC

=E−

E

=

4E

Potential gradient of AB=

5P

E

Potential gradient across BC=

5P

4E

Now the ratio of potential gradient =

4E/5P

E/5P

=1:4
