So this is the info that's given to us:
m1 = 4.87 x 10^24 kg
m2 = 4.87 x 10^24kg
F = 2.58 x 10^3 N
Now we can use this equation to solve:

You may be asking what g is. Well, it is equal to 6.67x10^-11 m3 /kg s2. G is gravitational constant. So :
As you can see we only have one variable, so we solve for r!

I hope this helps you out. I remember when I was first learning Newton's law<span> of universal </span><span>gravitation and I had some trouble. But with some practice, I got better. =) </span>

Answer:
The magnitude of magnetic field is 1.19 T and its direction magnetic is in negative x direction.
Explanation:
Given that,
Speed of a proton,
(due +x direction)
When it moves in the positive y direction it experiences a force of,
(due positive z direction)
We need to find the magnitude and direction of the magnetic field. The magnetic force is given by :

For direction :

So, the magnitude of magnetic field is 1.19 T and its direction magnetic is in negative x direction.
Electric potential energy, or Electrostatic potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system.
