A particle is moving under the influence of force F = [ i ^ − 2 j ^ ] N , is now moved from the point ( x , y , z ) = ( 2 , 1 , 3 ) m to the point ( x , y , z ) = ( 3 , 2 , 4 ) m . How much work is

Question

A particle is moving under the influence of force F = [ i ^ − 2 j ^ ​ ] N , is now moved from the point ( x , y , z ) = ( 2 , 1 , 3 ) m to the point ( x , y , z ) = ( 3 , 2 , 4 ) m . How much work is done by the force F during this time period? ( W = F . s )

The displacement is d = ([ 3 , 2 , 4 ] − [ 2 , 1 , 3 ]) m = [ 1 , 1 , 1 ] m . Then F ⋅ d = [( 1 ) ( 1 ) + ( − 2 ) ( 1 ) + ( 0 ) ( 1 )] N ⋅ m = − 1 J .]
