Q2. A cyclist is riding with a speed of 27 km/h. As he approaches a circular turn on the road of radius 80 m, he applies brakes and reduces his speed at the constant rate of 0.50 m/s every second. What is the magnitude and direction of the net acceleration of the cyclist on the circular turn?

A. 0.84 m

s^{- 2}

, 58.5

with the direction of velocity

B. 0.82 m

, 59.5

C. 0.86 m

s^{- 2}

, 54.5

^{\circ}

with the direction of velocity

D. 0.85 m

s^{- 2}

, 56.5

^{\circ}

with the direction of velocity

Answer : Option C
Explaination / Solution:

Speed of the cyclist, v = 27 km/h = 7.5 m/s
Radius of the circular turn, r = 80 m
Centripetal acceleration is given as:
ac = $\frac{v^{2}}{r} = \frac{(7.5)^{2}}{80} =$ 0.7 ms-2

The situation is shown in the given figure:

Suppose the cyclist begins cycling from point P and moves toward point Q. At point Q, he applies the breaks and decelerates the speed of the bicycle by 0.5 m/s2.

This acceleration is along the tangent at Q and opposite to the direction of motion of the cyclist.
Since the angle between ac and aT is 900, the resultant acceleration a is given by:
a = $\sqrt{(a_{c})^{2} + (a_{T})^{2}} = \sqrt{(0.7)^{2} + (0.5)^{2}}$
= $\sqrt{0.74}$ = 0.86 ms-2

tan θ = $\frac{a_{c}}{a_{T}}$
where θ is the angle of the resultant with the direction of velocity.
tan θ = $\frac{0.7}{0.5}$ = 1.4
θ = tan-1(1.4) = 54.56° with the direction of velocity

Q3. PPP stands for

A. People Power Parity

B. Purchasing Power People

C. Purchasing Power Parity

D. Purchasing Parity People

Answer : Option C
Explaination / Solution:

Purchasing Power Parity (PPP) is an economic theory that compares different countries' currencies through a market "basket of goods" approach. According to this concept, two currencies are in equilibrium or at par when a market basket of goods (taking into account the exchange rate) is priced the same in both countries.
