Vedclass · Answer

(C) The four fundamental forces in nature are gravitational, weak nuclear, electromagnetic, and strong nuclear forces.Their relative strengths are: $Strong \ Nuclear > Electromagnetic > Weak \ Nuclear > Gravitational$.$1.$ The gravitational force is the weakest force, while the strong nuclear force is the strongest.$2.$ The range of the gravitational and electromagnetic forces is infinite, whereas the range of the weak nuclear force is extremely small $(10^{-16} \ m)$ and the range of the strong nuclear force is also very small $(10^{-15} \ m)$.$3.$ Comparing the ranges, the range of the weak nuclear force $(10^{-16} \ m)$ is smaller than the range of the strong nuclear force $(10^{-15} \ m)$.Therefore, option $C$ is correct.

$(A)$ Torque	$(I)$ $Nms^{-1}$
$(B)$ Stress	$(II)$ $Jkg^{-1}$
$(C)$ Latent Heat	$(III)$ $Nm$
$(D)$ Power	$(IV)$ $Nm^{-2}$
