Attempt:

Attempt all the questions whether you know the answer or not.

Neat and clean:

Answer sheet should be neat and clean. Do not forget to cut the rough work done. Avoid overwriting.

Observant:

Always note the terms and digits from the question paper carefully.

Organised:

Question paper must be solved in serial order from 1 to 30. If you don`t know the solution for a particular question, leave the space for that.

Patience:

Never lose your patience during the exam. If you do not know the answer to any question, do not lose your patience. Move ahead and after completing rest of the questions, take a long breathe and think about the concepts involved in that particular question. This will definitely help you to recall some steps of that question.

Points to remember in the examination hall:

•Read the question paper with full concentration.

•First, attempt those questions which you are sure about.

•Mention the formula and put the values while solving your question as there is a criterion of step marking.

•Use pencil and scale to draw the figures. Never draw a figure with the use of a pen.

•If your writing is poor, then you can write leaving some space in between two words.

Dot or Scalar Product of Vectors

Dot Product of two vectors  A and B is defines as product of magnitude of the vectors and cosine of the angle between them.

A•B = |A||B|CosT, Where T is the angle between the vectors A and B. 

It is a scalar quantity

Special Cases

(I) If two vectors are perpendicular to each other their dot product is Zero.

(ii) If two vectors A and B are parallel their dot product is |A||B|.

If i, j, k are unit vectorsalong X, Y, Z axis respectively then 

i.i = 1

j.j = 1

k.k = 1

i.j = 0

j.k = 0

K.i = 0. 

 Note : Scalar product is commutative 

i.e. A.B = B.A
