The answer is:
The first option, the force tending to lift Rover is equal to 14.5 N.
<h2>Why?</h2>To calculate the force that is tending to lift Rover vertically, we need to calculate the vertical component force.
Since we know that the angle between the force and the ground is 29°, we can calculate the vertical component of the force using the following formula:
We are given that the force is equal to 30.0 N, so, calculating we have:
Also, we can calculate the horizontal component of the force using the following formula:
Hence, we have that the correct option is the first option, the force tending to lift Rover is equal to 14.5 N.
Have a nice day!
Answer:
q2 = -4.35*10^-9C
Explanation:
In order to find the values of the second charge, you use the following formula:
(1)
V: electric potential = 1.14 kV = 1.14*10^3 kV
k: Coulomb's constant = 8.98*10^9 Nm^2/C^2
q1: charge 1 = 8.60*10^-9 C
q2: charge 2 = ?
r1: distance to the first charge = 20.7mm = 20.7*10^-3 m
r2: distance to the second charge = 15.1mm
You solve the equation (1) for q2, and replace the values of the other parameters:
The values of the second charge is -4.35*10^-9C
