I really don’t know but I think it’s D
Answer:
Explanation:
Has an acceleration directed towards center of its path
- The length of its image =

Given,
length of object, 
We know, for flat refracting surface,
Image distance = object distance
So,
magnification is = 
length of the image,

Here, negative sign means inverted image.

The force per unit of length between two wires carrying current is

where I1 and I2 are the currents in the two wires, while r is the distance between them.
We can see from the formula that the force is proportional to the product between I1 and I2:

so, if we double both I1 and I2, we get a factor 4:

so, the force between the wires will be 4 times the original value.
When white light passes through a prism, violet is the color that is refracted the most.
