题目:如图1所示,待测区域中存在匀强电场和匀强磁场,根据带电粒子射人时的受力情况可推测其电场和磁场.图中装置由加速器和平移器组成,平移器由两对水平放置、相距为l的相同平行金属板构成,极板长度为l、间距为d,两对极板间偏转电压大小相等、电场方向相反,质量为m、电荷量为+q的粒子经加速电压U_0加速后,水平射入偏转电压为U_1的平移器,最终从A点水平射入待测区域.不考虑粒子受
Title: As shown in Figure 1, the uniform electric field and the uniform magnetic field exist in the test area, and the electric field and magnetic field can be inferred according to the force situation when the charged particle is shot in. The device in the figure consists of an accelerator and a translator It consists of two parallel metal plates placed horizontally and separated by l. The length of the plate is 1 and the distance is d. The deflection voltages between the two plates are equal in magnitude and in the opposite direction of the electric field. The mass is m and the charge is + q Acceleration of particles accelerated by U_0, the level of exposure into the deflection voltage U_1 translator, and finally into the test area from the level of A. Regardless of the particle
