Three dimensions. three point particles are fixed in place in an xyz coordinate system. particlea, at the origin, has massma. particleb, at xyz coordinates (2.00d, 1.00d,2.00d), has mass 2.00ma, and particle c, at coordinates (-1.00d, 2.00d, -3.00d), has mass 3.00mn. a fourth particled, with mass 4.00ma, is to be placed near the other particles. in terms of distance d, at what (a) x, (b) y, and (b) z coordinate should d be placed so that the net gravitational force on a from b, c, andd is zero?

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
