Step 1: If the electric and magnetic fields are parallel, the force on the charged particle due to the electric field will be in the same direction as the magnetic force.
Step 2: Since both forces act in the same direction, the charged particle will experience a uniform force, causing it to accelerate in a straight line.
If a charge \( q \) is placed at the centre of a closed hemispherical non-conducting surface, the total flux passing through the flat surface would

The electric potential \( V(x) \) in a region around the origin is given by \( V(x) = 4x^2 \, {volts}. \) .The electric charge enclosed in a cube of 1m side with its center at the origin is (in coulomb)
