Embibe Experts Solutions for Chapter: Laws of Motion, Exercise 4: Exercise-4

A vessel containing water is given a constant acceleration $a$ towards the right, along a straight horizontal path. Which of the following diagram represents the surface of the liquid?

The effective spring constant of two spring systems as shown in the figure will be:

The sum of the magnitudes of two forces acting at a point is $16 \mathrm{N}$. The resultant of these forces is perpendicular to the smaller force and has a magnitude of $8 \mathrm{N}$. If the smaller force is of magnitude $x$, then the value of $x$ is,

The resultant of two forces acting at an angle of $150°$ is $10 \mathrm{kg}$ wt and is perpendicular to one of the forces. The other force is :

A force of $6 \mathrm{kg}$ wt. and another of $8 \mathrm{kg}$ wt. can be applied together to produce the effect of a single force of:
