Answer:

E = 420.9 N/C

Explanation:

According to the given condition:

$Net\ Force = 2(Magnetic\ Force)\\Electric\ Force - Magnetic\ Force = 2(Magnetic\ Force)\\Electric\ Force = 3(Magnetic\ Force)\\qE = 3qvBSin\theta\\E = 3vBSin\theta$

where,

E = Magnitude of Electric Field = ?

v = speed of charge = 230 m/s

B = Magnitude of Magnetic Field = 0.61 T

θ = Angle between speed and magnetic field = 90°

Therefore,

$E = (3)(230\ m/s)(0.61\ T)Sin90^o$

two blocks are held together with a compressed spring between them on the surface of a slippery table .one block has three times

Marina CMI [18]

Explanation:

The initial kinetic energy $KE_0$ for both blocks is zero. Let $m_1= m$ and $m_2 =3m$ . So using the conservation law of linear momentum, we can write

$0 = m_1v_1 - m_2v_2$

$v_2 = \dfrac{m_1}{m_2}v_1 = \dfrac{m}{3m}v_1 = \dfrac{1}{3}v_1$

The final kinetic energies for the two masses are

$KE_1 = \frac{1}{2}m_1v_1^2 = \frac{1}{2}mv_1^2$

$KE_2 = \frac{1}{2}m_2v_2^2 = \frac{1}{2}(3m)(\frac{1}{3}v_1)^2 = \frac{1}{2}m(\frac{1}{3}v_1^2)$

Therefore, the ratio of their kinetic energies is

$\dfrac{\Delta KE_2}{\Delta KE_1} = \dfrac{\frac{1}{2}(\frac{1}{3}v_1^2)}{\frac{1}{2}v_1^2} = \dfrac{1}{3}$
