यदि सदिश राशि बल का मान, F = 3i + 4j - 5k तथा विस्थापन का मान, d = 5i + 4j + 3k हो तो कार्य की गणना ज्ञात करें ।
हल : बल, F = 3i + 4j - 5k तथा विस्थापन, d = 5i + 4j + 3k
कार्य = F.d
= (3i + 4j - 5k).(5i + 4j + 3k)
= 3 × 5 + 4 × 4 - 5 × 3
= 15 + 16 - 15
= 16 J
अतः दिए गए बल द्वारा किया गया कार्य होगा 16 जुल
