Which one of the following statements is correct
$10\, kg$ block is placed as shown, if $F = 50$ newton find friction force ............ $N$
Which of the following is a self adjusting force?
A $60\, kg$ body is pushed with just enough force to start it moving across a floor and the same force continues to act afterwards. The coefficient of static friction and sliding friction are $0.5$ and $0.4$ respectively. The acceleration of the body is ........ $m/{s^2}$
