2.如图所示,某同学用硬塑料管和一个质量为m的铁质螺丝帽研究匀速圆周运动,将螺丝帽套在塑料管上,手握塑料管使其保持竖直并在水平方向做半径为r的匀速圆周运动,则只要运动角速度合适,螺丝帽恰好不下滑,假设螺丝帽与塑料管间的动摩擦因数为μ,认为最大静摩擦力近似等于滑动摩擦力.则在该同学手转塑料管使螺丝帽恰好不下滑时,下列分析中正确的是()A.螺丝帽的重力与其受到的静摩擦力属于相互作用力B.螺丝帽受到塑料管的弹力方向水平向外,背离圆心C.此时手转动塑料管的角速度D.若塑料管的转动加快,螺丝帽有可能相对塑料管发生运动

8.如图所示,边长为L的等边三角形ABC,M、N两点分别为AB、BC边的中点,O点为等边三角形ABC的中心.在A、B两点固定电荷量均为+Q的点电荷,C点固定电荷为-Q的点电荷,下列说法正确的是A.O点的电场强度大小为k3QL^2B.M、N两点电场强度的大小关系为EM>ENC.M、N两点电势的火小关系为M<N-qD.将检验电猫一沿虚线从M点经O点移至N点,检验电荷的电势能一直增大
