A particle of mass 0.01 kg having position vector `vecr = ( 10 hati + 6 hatj)` meters is moving with a velocity `5 hati `m/s . Calculate its angular momentum about the origin.

A

` 0.1 bar(k) ` J/sec

B

`0.3 bar(i)`J/sec

C

`0.3 bar(k) `J/sec

D

`0.4 bar(k)` j/sec

Text Solution

Verified by Experts

The correct Answer is:
C
`bar(L) = bar(r ) xx bar(p) = (10hat(i) + 6 hat(j))xx 0.05 hat(i)`
