Dear student,
Work done= force dot displacement
you just need to take dot product
Work done= force dot displacement
you just need to take dot product

DEAR FRIEND,
WORK DONE =DOT PRODUCT OF FORCE AND DICPLACEMENT
SO,W=F.r
so (2i+3j+2k).(3i+4j+5k)
=6+12+10=28
so work done is 28 joules
thanks

WE KNOW THAT WORK IS A SCALA.
THEN WORK W= F.D
GIVEN f=2I+3J+2K ;r=3I+4J+5K
WE KNOW THAT DOT PRODUCTp { margin-bottom: 0.25cm; line-height: 120%; }
A.B = a1a2+b1b2+c1c2
F.D=(2×3)+(4×3)+(5×2)
=28
THERE FORE WORK =28J
