Question

A force of 20n applied parallel to d surface of a horizontal table is just sufficient to make a block of mass 4kg move on d table what is d co,efficient of friction between d surfacf of d block and d table .

Answer 1

Explanation:

Given:

Force applied on the block is F = 20 N.

Mass of the block is m = 4 kg.

The weight of the block is {eq}W = mg = 4 \times 9.8 \ N = 39.2 \...
