Answer:
h = 24.11 m
Explanation:
Given that,
The potential energy of the snowball is 520 J
The mass of the snowball is 2.2 kg
We need to find the height of the hill. The potential energy of an object is given by the formula as follows :
g is acceleration due to gravity
h is height of the hill
So, the height of the hill is 24.11 m.
(a) Force between the two charges
The electrostatic force between the two charges is given by:
where k is the Coulomb's constant, q1 and q2 the two charges, r their separation.
In this problem:
Substituting into the equation, we find
(b) direction of particle q2
Particle q2 wants to move in the direction of the force acting on it. The direction of the force depends on the relative sign of the two charges: like charges attract each other, opposite charges repel each other. In this case, the two charges are both positive, so they repel each other and q2 tends to move away from particle q1.
