F
q
E=k
Q
r
2
的叙述,不正确的是(   )

A:E=Fq是电场强度的定义式,F是放入电场中电荷所受的电场力,q是放入电场中电荷的电荷量,它适用于任何电场

B:E=Fq是电场强度定义式,F是放入电场中的电荷所受的力,q是产生电场的电荷的电荷量

C:E=kQr2是点电荷场强的计算式,Q是产生电场的电荷的电荷量,它不适用于匀强电场

D:在库仑定律的表达式 F=kq1q2r2 中, kq2r2 是点电荷q2产生的电场在点电荷q1处的场强大小,而 kq1r2 是点电荷q1产生的电场在q2处的场强大小

                                                                                                   自信的价值
        ①2001年5月20日,美国一位名叫乔治·赫伯特的推销员成功地把一把斧子推销给了小布什总统。布鲁金斯学会得知这一消息,把刻有“最伟大推销员”的一只金靴子赠予了他。
        ②布鲁金斯学会创建于1927年,以培养出类拔萃的推销员而著称于世。它有一个传统,在每期学员毕业时,设计一道最能体现推销员能力的实习题,让学员去完成。克林顿当政期间,他们出了这么一个题目:请把一条三角裤推销给现任总统。8年间,有无数个学员为此绞尽脑汁,可是,最后都无功而返。克林顿卸任后,布鲁金斯学会把题目换成:请把一把斧子推销给小布什总统。
        ③鉴于前8年的失败与教训,许多学员知难而退。因为现在的总统什么都不缺少,即使缺少,也用不着他们亲自购买;再退一步说,即使他们亲自购买,也不一定正赶上你去推销的时候。   
        ④然而,乔治·赫伯特却做到了。他认为,把一把斧子推销给小布什总统是完全可能的。因为,布什总统在得克萨斯州有一农场,那里长着许多树。于是他给布什写了一封信,说:有一次,我有幸参观您的农场,发现那里长着许多矢菊树,有些已经死掉,木质已变得松软。我想,您一定仍然需要一把不甚锋利的老斧头。现在我这儿正好有一把这样的斧头,它是我祖父留给我的,很适合砍伐枯树。假若您有兴趣的话,请按这封信所留的信箱,给予回复……最后布什就给乔治·赫伯特汇来了15美元。
        ⑤乔治·赫伯特成功后,布鲁金斯学会在表彰他的时候说:金靴子奖已空置了26年。26年间,布鲁金斯学会培养了数以万计的推销员,造就了数以百计的百万富翁。这只金靴子之所以没有授予他们,是因为我们一直想寻找这么一个人,这个人从不因有人说某一目标不能实现而放弃;从不因某件事情难以办到而失去自信。   
        ⑥在我们的生活中,不是因为有些事情难以做到,我们才失去自信;而是因为
