Gravitational pull between 2 objects is determined by which of the following?
2 answers:
Answer:
Both distance between and mass of the 2 objects
Explanation:
The gravitational pull between two objects is given by:
where
G is the gravitational constant
m1 is the mass of the first object
m2 is the mass of the second object
r is the distance between the two objects
From the formula, we see that the gravitational pull depends both on the distance between the two objects (r) and on their masses (m1, m2), so the correct answer is
Both distance between and mass of the 2 objects

Answer:
Explanation:
It is given that,
A planar electromagnetic wave is propagating in the +x direction.The electric field at a certain point is, E = 0.082 V/m
We need to find the magnetic vector of the wave at the point P at that instant.
The relation between electric field and magnetic field is given by :
c is speed of light
B is magnetic field
So, the magnetic vector at point P at that instant is .
