Answer:
The magnitude of the electric field are and
Explanation:
Given that,
Radius of inner shell = 11.0 cm
Radius of outer shell = 14.0 cm
Charge on inner shell
Charge on outer shell
Suppose, at r = 11.5 cm and at r = 20.5 cm
We need to calculate the magnitude of the electric field at r = 11.5 cm
Using formula of electric field
Where, q = charge
k = constant
r = distance
Put the value into the formula
The total charge enclosed by a radial distance 20.5 cm
The total charge is
Put the value into the formula
We need to calculate the magnitude of the electric field at r = 20.5 cm
Using formula of electric field
Put the value into the formula
Hence, The magnitude of the electric field are and
Answer:
The answer is "512 J".

Answer:B
Explanation:
For work to be done, the object must move some distance as a result of a force
Bulimia nervosa is similar in many ways because the individual is obsessed with their weight and wants to continuously lose weight to achieve their idea of a 'perfect' body shape. But with bulimia, there are periods of binging and purging. This means that the individual with bulimia may go through a period where they eat an excessive amount of food and then purge by using exercise, medications or vomiting to get rid of the food.
