Vm=4i+4j+5k
Vo=3i+4j+5k
mirror is perpendicular to z axis
so movement of mirror along x,y axis does not affect only movement of object along x,y axis affect
so V can confirm that Vimage is 3i+4j+mk
now V shld find m
using Vo-Vm=Vm-Vi along z axis
5-5. =5-Vi
Vimage = 5 along z axis
so final answer is 3i+4j+5k
Vo=3i+4j+5k
