Question

consider a force vector F=i+j+k. Another vector perpendicular of F is.

Answer 1

if any vector as displacement vector is perpendicular to the force vector , then work done by the force vector will always zero

Answer 2

Answer:

F = I +j + k

qnd it is perpendicular to F then

when we do dot product of this vector then it will come ZERO

F.s cos@ = 0

I + j + k . s Cos@ = 0

solve the rest
