If we take an object to 20m. Height from the surface earth,what will be the value of potential energy of that object. |
| Answer» HEIGHT of the BODY from the ground = 20mTo Find :Value of POTENTIAL energy of the object.Solution :❖ Potential energy the energy which is possessed by a body by VIRTUE of its position.It is a scalar quantity having only magnitude.SI unit : JSI unit : [M¹L²T‾²]Value of potential energy at the reference point is taken zeroHere potential energy of body at ground is zero.» Potential energy of body of mass m at a height h from the ground is given by, U = m g hwhere g denotes gravitational accelerationLet mass of the body be m.By substituting the given values;➙ U = m g h➙ U = m × 10 × 20➙ U = 200 m Joule | |
