A constant force of 12 N in the positive x direction acts on a 4.0-kg object as it moves from the origin to the point $( 6 \tilde { \mathbf { i } } - 8 \tilde { \mathbf { j } } )$ m.How much work is done by the given force during this displacement?
A)+60 J
B)+84 J
C)+72 J
D)+48 J

The Answer is C

A Constant Force of 12 N in the Positive X (6i~−8j~)( 6 \tilde { \mathbf { i } } - 8 \tilde { \mathbf { j } } )(6i~−8j~​)

A Constant Force of 12 N in the Positive X $( 6 \tilde { \mathbf { i } } - 8 \tilde { \mathbf { j } } )$
