Question

a square glass plate 9 5 cm long and 0 5 cm thick is suspended so
that its lower edge is in contact with water in a trough calculate
the force due to the surface tension acting on the plate surface
tension = 72 dynes/cm

Kiruthika · Accepted Answer

Dear student,
The force due to surface tension on glass plate is F=4lT+W
Weight of glass plate is
W=l×b×t×density =108 3g
Force due to surface tension is given by
F=4×9 5×72+108 3F=2844 3dyne
