Let a,b,c be non coplanar unit vectors , equally inclined to one another at an angle θ. If a x b+b x c = pa+qb+rc. Find scalars p q r in terms of θ
1. the distance covered by a body in each second exceeds the distance covered by it in the previous second by a. If it covers a distance a/2 in first second from start, total distance covered in first t seconds of the motion is
sir please explain me the formula you will use to solve this!!!
2. Two forces (p+q) and (p-q) make an angle 2β with one another and their resultant makes an angle α with the bisector of the angle between them. Then the value of p ⁄ q is
Sir the answer is 2tanβ ⁄ tanα.
Is area always a vector quantity or it can be a vector quantity?
generally it is scalar but in the measurement of flux through a surface it is considered a vector perpendicular to the surface with same magnitude
line AB intersects CD internally in the ratio K : 1 where K is undefined , these line may be ( 1) concurrent , (2) intersecting , (3) skew < (4) all of these . explain plese ?
I think it will be skew because skew lines do not intersect in real points
