Dos cargas puntuales q1 = −50μC y q2 = +30μC se encuentran encima de una recta, Determine: a) la distancia que se deben separar las
cargas q1 y q2 para que la fuerza eléctrica entre ambas cargas sea de 10
N , b) a que distancia la fuerza se duplica c) a que distancia la fuerza se
quintuplica

Can someone explain to me how to do this problem ?

Part a determine the magnitude of the x component of f using scalar notation. fx f x = nothing lb request answer part b determine the magnitude of the y component of f using scalar notation. fy f y = nothing lb request answer part c determine the magnitude of the z component of f using scalar notation. fz f z = nothing lb request answer provide feedback figure1 of 1a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component. a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component.
