Answer:
Explanation:
To find the force we proceed by defining the variables we have,
The charge on one of the balls is defined under the equation,
Due to the height we need to calculate the potential energy at the height of 115m,
The kinetic energy would be given by
From the law of conservation we equate the two equations
In this way we now calculate the strength of the particle
Answer:
Real and inverted
Explanation:
Magnification of a lens is defined as the ratio of the height of the image to the height of the object.
Where
h' is the height of image
h is the height of the object
It is also defined as the ratio of image distance to the object distance.
Here, m = -0.6
Negative sign shows the image is inverted. So, the formed image will be real and inverted.
