If`A = 3hati +4hatj and B= 7hati+24hatj` the vector having the same magnitude as B and parallel to A is

Text Solution

Verified by Experts

The vector parallel to ` vecA ` and having magnitude of ` vecB ` is ` vecC = | vecB |(vecA)/(|barA|)= |vecB| vecA `
` B= sqrt( 7^2 + 24 ^2 )= 25 and hatA = ( vecA)/( A) = (3 hati + 4 hatj )/( sqrt( 3^2 + 4^2)) =1/5 ( 3 hati + 4hatj )`
` vecC = 25 xx (1)/(5) ( 3hati + 4hatj ) = 15 hati + 20 hatj `
