दी गई व्यवस्था मे प्रतिबिम्ब का वेग ज्ञात कीजिए।

Explanation

`vecV_(IM) = -vec(V)_(OM) = vecV_(IG) `( `because` दर्पण विराम पर है)
`vecV_(IG) = -3 hati`
(B) `vecV_(OG) = 3hati , vecV_(Mg) = 1hati implies vecV_(OM) = 2hati`
अतः `vecV_(IM) = - 2 hati`
अब `vecV_(IG) = vecV_(IM) + vecV_(MG) = -hati`
(C) `vecV_(OM) = 5hati , vecV_(IM) = -5hati ` so
`vecV_(IG) = -5 hati + 2hati = -7hati`
(D) x दिशा के अनुदिश
`(vecV_(IM))_x = -7 hati, (vecV_(IG))_x = -11 hati`
अतः `vecV_(IG) = -11hati + 4hatj`
