Answer:
Explanation:
The electric force between two charged objects is given by:
where:
k is the Coulomb's constant
q1 and q2 are the charges of the two objects
r is their separation
In this problem:
q1 = 2.0 C
q2 = 1.0 C
r = 2 m
So, the electric force is
Answer: All the planets in our solar system rotate around it without the sun itself moving therefore all the planets make a cicular shape and the sun is in the middle
Explanation:
The box accelerates at 1. 0 m/s² to the right because the net force is 17N to the right . This statement clearly depicts the relation between force and acceleration. Hence option A is correct.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate of change of the velocity of the body. Its unit is m/sec².It is a vector quantity. It requires both magnitudes as well as direction to define.
According to Newton's second law of motion, the net force acting on the body is equal to the product of mass and acceleration of the body.
The direction of acceleration is in the direction of net force acted.
Hence option A is correct.
