Q. Explain about Linear Isoquant?

: In this case, isoquant would be straight lines as in Figure below. This type presumes perfect substitutability of factors of production. In this case, capital and labour are perfect substitutes, which is, the rate at which labour can be substituted for capital in production is constant.

Linear Isoquant

This isoquant evinces that a given commodity can be produced by using only capital or only labour or by an infinite combination of and labour and capital. At point A on the isoquant level of output can be produced with capital alone (which means without labour). In the same way, point B indicates that same level of output can be generated with labour alone (which means without any capital). This is unrealistic since labour and capital aren't perfectly substitutable.
