23. Z UNIVERSAL JOINT A uniform bar is mounted so its midpoint is anchored at the origin of a three-dimensional coordinate system. The bar can rotate in any direction about this mounting. A force F of 3i+ 4j+5k acts on one end of the bar. The bar will remain stationary if acting on its other end there is a force of (A) 31+4j+5k
