If `veca` is a non-zero vector of magnitude a and `vec(lamda a)` a is a unit vector, find the value of `lamda`

If veca is a non zero vector of magnitude abs(veca) and lambda is a non zero scalar, then find the value of lambda for which lambda veca is a unit vector.

If vec(a) is a non-zero vector and m is a non-zero scalar, then m vec(a) is a unit vector if

If vec a is a non-zero vector of magnitude ‘a’ and λ a non-zero scalar, then λ vec a is unit vector if λ =1

If vec a is a non-zero vector of magnitude ‘a’ and λ a non-zero scalar, then λ vec a is unit vector if λ = - 1

If vec a is a non-zero vector of magnitude ‘a’ and λ a non-zero scalar, then λ vec a is unit vector if a = 1/ |λ|

If vec a is a non-zero vector of magnitude ‘a’ and λ a non-zero scalar, then λ vec a is unit vector if a = |λ|

If veca is a non-zero vector of modulus a and m is a non-zero scalar, then ma is a unit vector if

If veca is a non zero vector of magnitude 'a' and lambda a nonzero scalar, then lambda vec a is unit vector if

If veca is a non-zero vector of magnitude 'a' and 'lambda' is a non-zero scalar, such that |lambdaveca|=1 , then :
