Question

Explain why, the tip of a sewing needle is sharp.

Solution

The tip of a sewing needle is sharp because the area under the pointed end of the sharp needle is very small. Pressure exerted by a sharp needle is more on the cloth and can pierce easily through the cloth.

  Is there an error in this question or solution?
