The diagram below shows two metal spheres taken from Newton's cradle and separated by a distance of 0.1 meters. The charge on sphere A is +6.0 x 10- coulomb and the
charge on sphere B is +3.0 x 10-5 coulomb.
0.1 m
Which statement best describes the electrical force on the spheres?

volleyball players can not touch the net while the ball is in play

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
