下列关于自然界中的四种基本相互作用的描述正确的是（ ）
A．一切物体之间都存在着相互作用的吸引力
B．强相互作用存在于宏观物体之间，而弱相互作用存在于原子核内部
C．电荷间的相互作用、磁体间的相互作用在本质上是同一种相互作用的不同表现
D．原子核内部的带正电的质子之间存在着斥力，但原子核仍能紧密的保持在一起，是由于万有引力作用的结果
A、宇宙万物任何两个物体之间都存在着相互作用的吸引力，这种引力叫做万有引力．故A正确．
B、强相互作用和弱相互作用都存在于微观物质内部，比如原子核内部．故B错误．
C、电荷间的相互作用、磁体间的相互作用在本质上是电磁相互作用的不同表现．故C正确．
D、原子核内部的带正电的质子之间存在着斥力，但原子核仍能紧密的保持在一起，不是由于万有引力作用的结果，而是核力作用的结果．故D错误．
