An insulating sphere of radius 13 cm has a uniform charge density throughout its volume. 13 cm 21.6 cm 7.5 cm p If the magnitude of the electric field at a distance of 7.5 cm from the center is 78400 N/C , what is the magnitude of the electric field at 21.6 cm from the center? Answer in units of N/C

The value is

Explanation:

From the question we are told that

The radius is

The electric field is at a distance

Generally the electric field at a distance is mathematically represented as

Note: the reason we are using this

formula is because

Here k is the coulomb constant with value

=>

Generally the electric field at a distance is mathematically represented as

Note: the reason we are using this

formula is because

Now dividing

=>

=>

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
