Answer:
The ratio m_2/m_1 of the masses is 9.745
Explanation:
Formula for frequency when mass m_1 is hung on the spring:
where:
k is the spring constant
Formula for frequency when mass m_2 is hung on the spring along with m_1:
where:
k is the spring constant.
In order to find ratio m_2/m_1, Divide the above equations:
On Solving the above equation:
The ratio m_2/m_1 of the masses is 9.745
The resultant is maximum when the angle between the two vectors is zero
Explanation:
The formula to calculate the resultant of two vectors A, B is the following:
where
A is the magnitude of vector A
B is the magnitude of vector B
is the angle between the directions of A and B
This formula can be derived by applying the parallelogram law.
From the formula, we observe that:
- When (vectors A and B parallel),
. so the resultant becomes simply
- When (vectors A and B perpendicular),
, so the resultant becomes
- When (vectors A and B anti-parallel),
, so the resultant becomes
By looking at the three cases and at the formula, we see that the maximum value of the resultant is when the angle between the two vectors is zero, since in that case the resultant is simply obtained by adding the magnitudes of the two vectors.
