ICS Part 1 Physics English Medium Chapter 2 Online Short Questions Test with Answers

Question # 1

Define and explain the scalar product?

Ans 1:

Question # 2

Explain how cranes are able to light very heavy load without toppling ?

Ans 1: We know that object with a high centre of gravity are likely to be unstable . For this reason, the bases of the cranes are made low and heavy, so that centre of gravity remains low.
The torque produced by a heavy load lifted by a crane is counterbalanced by its heavy body and large moment arm. Thus the cranes do not topple when they carry heavy loads.

Question # 3

Discuss the subtraction of vector ?

Ans 1:

Question # 4

Define and explain vector product ? (or) Cross Product.

Ans 1:

Question # 5

What is the minimum number of unequal vector in to a null vector?Explain

Ans 1: The minimum number of unequal vector to result in to a null vector must be three. If we add three vector of unequal magnitude in such a way that they forms the sides of a triangle, then their resultant must be zero.
In the given figure three vectors A, B, and C are added according to head to tail rule and they form the side of a triangle. Now for getting their resultant, we will combine the tail of A with the head of C which already coincides each other. Thus we get a null vector or zero vector as a resultant
R= A+B+C = 0

Question # 6

Two vector of magnitude 10 each making angle 180^oWith each other.Find the magnitude of their resultant.

Ans 1: We know that the sum of two vectors which are equal in magnitude and opposite in direction is zero.
Two vectors of magnitude 10 each making angle 180^oWith each other are in opposite direction.Therefore, the magnitude of their resultant will be equal to zero.

Question # 7

Define and explain position vector ?

Ans 1:

Question # 8

Can a body rotate about its center of gravity under the action of its weight?

Ans 1: No a body cannot rotate about its center of gravity under the action of its weight.Because the whole weight of the body acts on its center of gravity. The moment arm is zero in this case .

Question # 9

Define the following?
Parallel vectors
Equal vectors
null vectors
Anti parallel vectors
Negative of a vectors

Ans 1: Parallel Vectors:Vectors are said to be parallel to each other if they are acting in the same direction.
Anti Parallel Vectors:Vectors are said to be anti parallel to each other if they are acting in opposite direction.
Equal vectors:Two vectors are said to be equal, if they have the same magnitude and same direction.
Negativeof a vector:Negative of a vector is that vector whose magnitude is the same to that of the given vector but opposite in direction.
Null Vector:A vectors whose magnitude is zero is known as null vector.

Question # 10

Define unit vector?

Ans 1: A vector whose magnitude is one is known as unit vector
