(a) It is positively charged (b) It is negatively charged (c) It is electrically neutral (d) Object X may be positively charged, but it is possible it is also electrically neutral with an induced charge separation​

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.
