A particle is acted on by two torques about the origin: τ→, has a magnitude of 6.5 N⋅m and is directed in the positive direction of the x axis, and τ→2 has a magnitude of 2.3 N⋅m and is directed in the negative direction of the y axis. In unit-vector notation, find dℓ→/dt, where ℓ→ is the angular momentum of the particle about the origin. Number i^ j^ Units
