Answer:in this situation we have during the two tiny spheres of masks, 5.8 mg carry Charges of equal magnitude 30 77 Nano column but opposite in sign They are tied to the same ceiling hook by light in spring of 2.53 m. It is known that when they original uniform electric village applied that is directed to the left. The angle between the springs is 58°. Then we have to find the value of E. So given that the mass M is 5.8 mg, that is 5.8 into 10 to the power -3 g. And This is five and we have the charge that is Q. Is 77 and a column. So this is 77 into 10 to the power -9 columns. The length of the string is 0.53 m. And the angle between the spring.
