Question

a particle is displaced 2i-3j+k to another position 3i+2j-2k under the action of the force 2i+j-k the workdone by tge force in arbitory unit is​

Answer 1

Explanation:

5i-1i-k

root of(25+1+1)

=5.2

2i+j-k

=root of (4+1+1)

=2.4

W=displacement × force in direction of displacement

so W =2.4×5.2

=12.48 J
