A unit vector is a vector of unit magnitude and a particular direction.

They specify only direction. They do not have any dimension and unit.
In a rectangular coordinate system, the x, y and z axes are represented by unit vectors, î,ĵ andk̂
These unit vectors are perpendicular to each other.
|î| = |ĵ | = |k̂| = 1

Explain the central problem of what to produce and in what quantities

Posted by Kulraj Sachdeva 6 years, 8 months ago

CBSE > Class 11 > Economics

1 answers

Yogita Ingle 6 years, 8 months ago

As there is the problem of choice, the economy has to decide which goods and services are to be produced. For example, which of the consumer goods such as wheat, rice, cloth are to be produced and which of the capital goods such asmachines and tools are to be produced.

When an economy has taken a decision as to what goods or services to be produced, then it has to be about its quantity. How much of consumer goods and capital goods are to be produced. For example, if an economy decides to produce rice and wheat within a given period with limited resources then it will have to using less of machineries.
