Pls ans briefly explain

The force of gravitational will decreases by a factor of 4

Explanation:

The given parameters are;

The symbol that represents the given mass = m

The mass of the circular ring = M

The initial distance of the mass "m" located at the point P from the center O = h

The final distance of the mass "m" when moved further away from point O = 2·h

Given that h = r, we have;

Therefore, when OP = 2·h, we have;

OP = 2·r and the new gravitational force, F₂, is given as follows;

Therefore, when the mass, m, is removed such that OP = 2h, the value of the gravitational force decreases by a factor of 4.

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5
