Two forces `vecF_(1)=5hati+10hatj-20hatk and vecF_(2)=10hati-5hatj-15hatk ` act on a single point. The angle between `vecF_(1) and vecF_(2)` is nearly

The resultant of the forces vecF_(1)=4hati-3hatj and vecF_(2)=6hati+8hatj is

If vecF=hati+2hatj-3hatk and vecr=2hati-hatj+hatk find vecrxxvecF

If vecF=2hati+3hatj-hatk and vecr=hati-hatj+6hatk find vecrxxvecF

The resultant of the forces vecF_(1) = 4hati-3hatj and vecF_(2) = 6hati + 8hatj is

The resultant of the forces vecF_(1) = 4hati-3hatj and vecF_(2) = 6hati + 8hatj is

If vecF = 3hati + 4hatj+5hatk and vecS=6hati +2hatj+5hatk , the find the work done.

If vecF=3hati-4hatj+5hatk " and " vecS=6hati+2hatj+5hatk , the find the work done.

If vecF = 3hati - 4hatj+5hatk and vecS=6hati +2hatj+5hatk , the find the work done.
