If the vectors `(hati+hatj+hatk)` and `3 hati` form two sides of a triangle, then area of the triangle is :

Text Solution

Verified by Experts

The correct Answer is:
`10^(-30)` star joule

Dimension of joule `=ML^(2)T^(-2)`
value of 1 joule in star system
`=(10^(-20))(10^(-8))^(2)(10^(-3))^(-2)=10^(-30)` star joule
