Answer:
False.
Explanation:
Yes the magnitude of a vector is always positive , but a vector consists of
when two vectors are added their direction may be opposite to each other For example-

,
then their resultant

This resultant vector's x and y component equal to y and x component of vector b so its magnitude will be equal to magnitude of vector b.
Therefore, the resultant magnitude not necessary equal to the magnitude of either vector.
The net force on q₃ will be 17.51 N. The net force is the algebraic sum of the two forces on the pleading q₃
<h3 /><h3>What is Columb's law?</h3>
The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The force,by the charge q₁ on the q₃;

The force,by the charge q₂ on the q₃;

The net force is the sum of the two forces;

Hence, the net force on q₃ will be 17.51 N.

Answer:
2.35 seconds
Explanation:
Remark
This is a question where direction matters. Let us call down + and up minus. It won't matter. The answer will be the same.
Formula
a = (vf - vi)/t
Givens
a = 9.8 m/s^2
vi = - 15 m/s
vf = 8m/s
Solution
9.8 = (8 - - 15)/t Multiply both sides by t
t * 9.8 = 23 Divide by 9.8
t = 23/9.8
t = 2.35 s
Answer:v
Explanation:
Given
Initially spring mass system is moving towards right with velocity 
Now if the spring is released left block moves towards left with a velocity 
As there is no external force applied on the system therefore the change in linear momentum is zero i.e. it is conserved
so center of mass continue to move towards the right with velocity v or we can say right block moves towards right with velocity
and left block moves with velocity
