The specific heat capacity of the substance is
Explanation:
When an object of mass m is supplied with a certain amount of energy Q, its temperature increases according to the equation:
where
m is the mass of the object
is its specific heat capacity
is the increase in temperature of the object
In this problem, we have
m = 50 g
Therefore, we can solve for to find its specific heat capacity:

The electrostatic force between two point charges is given by:
where
is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between them
In our problem, charge 1 is
while charge 2 is
and their distance is
r=5.0 cm=0.05 m
So, the electrostatic force between them is
And the negative sign means the force is attractive, because the two charges have opposite sign.
