Two forces whose magnitudes are in ratio of 3:5 give a resultant of 35N. If the angle of inclination is 60°, calculate the magnitude of each force.
Correct Answer
B. 15N and 25N
Explanation
Explanation: P = 3x and Q = 5x R = 35N θ = 120°
R = √(P2+ R2+ 2PQcosθ)
35 = 7x or x = 35/7 = 5
P =( 3x5 )= 15N
Q =( 5x5 ) = 25N.

READ THE PARAGRAPH CAREFULLY AND ANSWER THE FOLLOWING QUESTIONS.
And yet it is one of the simplest ideas that anyone ever had. Here I want to persuade you how evolution explains the beginning of life on earth. Darwin uncovered the theory of evolution and the method of natural selection. The idea of evolution is probably one of the most important ideas that anyone has ever had. Today, thanks to Darwin, we know why life is the way it is. We can predict how life will be in the future. We can even postulate about the life on other planets. How amazing is that! Now answer the following questions:
Q31.What is the topic of the paragraph?
Correct Answer
C. It tells us about the origin of life.
Explanation
Although by evolution, we can make predictions is also mentioned in the paragraph but it is not the central idea of the paragraph. The central idea is usually at the beginning or you will find a few sentences that are focussed on the idea.
