Two identical conducting spheres are separated by a fixed center-to-center distance of 46 cm and have different charges. Initially, the spheres attract each other with a force of 0.099 N. The spheres are now connected by a thin conducting wire. After the wire is removed, the spheres are positively charged and repel one another with a force of 0.031 N. Find (a) the final and (b) the initial charges on the spheres g.

magnified images possible images can be real = projected onto a screen

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
