Answer: attractive
Explanation:
According to Newton's law of Gravitation, the gravitational force
exerted between two bodies of masses
and
and separated by a distance
is equal to the product of their masses and inversely proportional to the square of the distance:
Where:
is the Gravitational Constant
and
are the masses of the objects
is the distance between the objects
It should be noted: this force is a central force and is attractive.
Answer:
Angular position of the first minimum is 0.27 degree
Explanation:
As we know by the formula of single slit diffraction pattern

here we have
a = d = 0.000125 m
for m = 1

now we have

Answer:
Work is measured as the product of force and the displacement in the direction of the force. Work = force × displacement in the direction of the force.
