Abarbell is 1.5 m long. three weights, each of mass 20 kg, are hung on the left and two weights of the same mass, on the right. the width of each weight is 4 cm and each group of weights is placed 4 cm from the ends. where is the center of mass of the barbell as measured from the mid-point, m, of the bar? the bar is of uniform mass and has mass 5 kg, and the retaining collars are of negligible mass. take to the right as positive.

r = -11.6 cm

Explanation:

As we know that the position of center of mass is given as

now we know that three masses are on the left while two are on the right

position of left most mass with respect to the center of the rod is given as

Now we will have

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
