To find the position of the center of mass of the system, we can use the principle of symmetry. Since the rigid rod is of negligible mass and the two particles have different masses, the center of mass will lie closer to the heavier particle.
Let's assume that the center of mass is at a distance x from the 5 kg particle.
Calculating the center of mass:
We can calculate the center of mass using the formula:
x_cm = (m1 * x1 + m2 * x2) / (m1 + m2)
where m1 and m2 are the masses of the particles, and x1 and x2 are the distances of the particles from the center of mass.
In this case, m1 = 5 kg, m2 = 10 kg, x1 = x (distance from the 5 kg particle), and x2 = 1 - x (distance from the 10 kg particle).
Substituting these values into the formula, we get:
x_cm = (5 * x + 10 * (1 - x)) / (5 + 10)
= (5x + 10 - 10x) / 15
= (10 - 5x) / 15
Since the center of mass is closer to the 10 kg particle, we know that x_cm < 1="" (the="" length="" of="" the="" />
Simplifying the equation further, we have:
10 - 5x < />
-5x < />
x > -1
Since x must be greater than -1 and less than 1, we can conclude that the center of mass is approximately 0.67 m or 67 cm from the 5 kg particle.
Therefore, the correct answer is option A) 67 cm.
Let's assume that the center of mass is at a distance x from the 5 kg particle.
Calculating the center of mass:
We can calculate the center of mass using the formula:
x_cm = (m1 * x1 + m2 * x2) / (m1 + m2)
where m1 and m2 are the masses of the particles, and x1 and x2 are the distances of the particles from the center of mass.
In this case, m1 = 5 kg, m2 = 10 kg, x1 = x (distance from the 5 kg particle), and x2 = 1 - x (distance from the 10 kg particle).
Substituting these values into the formula, we get:
x_cm = (5 * x + 10 * (1 - x)) / (5 + 10)
= (5x + 10 - 10x) / 15
= (10 - 5x) / 15
Since the center of mass is closer to the 10 kg particle, we know that x_cm < 1="" (the="" length="" of="" the="" />
Simplifying the equation further, we have:
10 - 5x < />
-5x < />
x > -1
Since x must be greater than -1 and less than 1, we can conclude that the center of mass is approximately 0.67 m or 67 cm from the 5 kg particle.
Therefore, the correct answer is option A) 67 cm.
