Dos cargas positivas se repelen con una fuerza de 3N. Si la primera tiene una magnitud de 6x10 a la -4 C y la otra es de 5x10 a la -4 C. ¿Cuál debe ser la distancia entre las cargas?¿Qué sucederá con la distancia si la fuerza se triplica? Elabora tu figura.

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
