Two strings of the same material and the same area of cross-section are used in sonometer experiment. One is loaded with 12kg and the other with 3 kg. The fundamental frequency of the first string is equal to the first overtone of the second string. If the length of the second string is 100 cm, then the length of the first string is

A metallic sphere A isolated from ground is charged to + 50 mu C . This sphere is brought in contact with other isolated metallics sphere B of half the radius of sphere A.The charge on the two sphere will be now in the ratio.

A uniform sphere of weight W and radius 5 cm is being held by string as shown in the figure. The tension in the string will be
