Answer:
3000J
Explanation:
The gravitational energy for any object is given by E=mgh
where m is mass, g is gravitational field strength anf h is height above ground
The correct answer you should be looking for is complementary. :)
Answer:
A. 181.24 N
Explanation:
The magnitude of hte electrostatic force between two charged objects is given by the equation

where
k is the Coulomb's constant
q1, q2 are the magnitudes of the two charges
r is the separation between the charges
In this problem, we have:
is the magnitude of the 1st charge
is the magnitude of the 2nd charge
r = 2.5 cm = 0.025 m is the separation between the charges
Therefore, the magnitude of the electric force is:

So, the closest answer is
A) 181.24 N
Electrostatic forces are non-contact forces; they pull or push on objects without touching them
