Force F applied on a body is written as F =( n F ) n + G , where n is a unit vector The vector G is equal to

Options

  1. An F
  2. Bn ( n F )
  3. C( n F ) F /| F |
  4. D( n F ) n

Correct answer

D. ( n F ) n

Step-by-step solution

( n F ) n =-[ n ( n F )]=-[ n ( n F )- F ( n n )]= F - n ( n F )]= G
