Question

given that force (5icap+7jcap-3kcap)N acts on a particals at position (Icap+jcap+kcap)m find torque of this force on the particle about origin

​

Answer 1

Answer:

torque (vector) = r(vector) × F(vector)

Explanation:

torque = i j k ( in matrix form)

5 7 3

1 1 1

= i(7-3)(cap) + j(5-3)(cap) + k(5-7)(cap)

=4i(cap) + 2j(cap) - 2k(cap)
