1 PM JEE Mains 2020 - Maths | Vectors and 3D Geometry By Shahid Sir | JEE Score Booster Course

If the direction ratio of two vectors are connected by the relations a+b+c=0 and a^(2)+b^(2)=c^(2). then the angle between two vectors

Velocity vector and acceleration vector in a uniform circular motion are related as

Velocity vector and acceleration vector in a uniform circular motion are related as

The vectors a and b are not perpendicular and c and d are two vectors satisfying b xx c=b xx d and a.d=0. The vectors d is equal to

For figure the correct relation is (all vector have same magnitude).

Representation of a Relation in (d) lattice form

The position vectors of four points A,B,C,D lying in plane are a,b,c,d respectively.They satisfy the relation |a-d|-|b-d|-|c-d| ,then the point D is

The terms 'microinjection' , 'biolistics' and 'disarmed plathogen vector' are related to
