黑龙江省大庆市肇源县2024-2025学年度上学期期初质量检测（初二）-(物理)试卷答案第一部分

10.如图所示,在竖直平面内存在水平向右的匀强电场,电场强度的大小为E,将一质量m=0.5kg、电荷量q=1C的小球用一根长L=0.2m,不可伸长的绝缘轻绳悬挂在O点,小球静止时的位置记为A点,此时轻绳与竖直方向的夹角=45^。,现将小球向左拉至与O点等高处(如图所示),此时轻绳恰好伸直且无拉力,然后将小球由静止释放,轻绳在绷紧的瞬间会使沿绳方向的速度突变为0,重力加速度g=10m/s^2,不计空气阻力,小球可视为质点,关于小球的运动,下列说法正确的是A.匀强电场的电场强度为N/C5B.小球由静止释放后,第二次经过最低点时的速度大小为22m/sC.小球运动到A点时的速度大小为4m/sD.小球从与O点等高处到A点的过程中,小球增加的机械能为22j

在直角坐标系:xO3y中,x轴上A处固定电量为+Q的点电荷,B处固定电量为-q的点电荷,Q=2q。规定无穷远处电势为零,坐标原点处的电势恰好为零。已知取无穷远处电势为零时,点电荷在某点形成的电势,=kqr,其中是该点到点电荷的距离。下列说法正确的是()A.除了坐标原点O和无穷远处外,x轴上还有一个电势为零的点B.除无穷远处外,y轴上还有两个电势为零的点C.除了坐标原点O外,在y轴上还有一个点的电场强度方向指向B点D.把一正试探电荷放在x轴上某点处,除无穷远处外该电荷可以静止的位置有两个
