True / False

When a razor blade floats on water, then the force of surface tension acts on the circumference of the blade acting tangentially to the liquid surface.

ATRUE
Correct Answer
BFALSE

Solution

When a razor blade floats on water, three forces act on the blade :
(i) Reaction on blade exerted by the liquid surface acting vertically upwards
(ii) Force of the surface tension on circumference of the blade acting tangentially to the liquid surface
(iii) Weight of the blade acting vertically downwards
