Question 41 MarkMagnetic ForceAnswerThe force exerted by a magnet to pull/push a metallic object is called magnetic force.View full question & answer→
Question 51 MarkGravityAnswerEvery object in the universe, whether small or large, exerts a force on every other object. This force is called the force of gravity or just gravity.View full question & answer→
Question 61 MarkGravitational ForceAnswerThe force exerted by the earth to pull the objects towards itself is called the force of gravity.View full question & answer→
Question 71 MarkFrictionAnswerThe force of friction always acts on all the moving objects and its direction is always opposite to the direction of motion.View full question & answer→
Question 81 MarkForceAnswerSimply a push or pull exerted by an object on another is a force.View full question & answer→
Question 91 MarkElectrostatic ForceAnswerWhen a charged body, either having a $(+)$ or $(-)$ charge, exerts force on another charged or uncharged body, that force is known as electrostatic force.View full question & answer→
Question 101 MarkContact ForceAnswerA force that can be applied only when it is in contact with an object is called a contact force. For example, hammering a nail.View full question & answer→
Question 111 MarkAtmospheric PressureAnswerThe pressure exerted by atmospheric air around us is known as atmospheric pressure.View full question & answer→
Question 121 MarkElectrostatic forceAnswerA force exerted by a charged body on another charged or uncharged body is known as electrostatic force.View full question & answer→
Question 131 MarkPressureAnswerThrust per unit area is called pressure. So, pressure = force/area on which it acts.View full question & answer→
