Question1
In an assured region of space there is uniform electric field 'E' and uniform magnetic field 'B' both directed along Z-axis. A particle of charge 'q' and mass 'm' is injected at time't=0' with the velocity 'u' along X-axis. Discover the velocity of particle at time't'.
Question2
High-speed stroboscopic photographs show that the head of a 180-g golf club is travelling at 49 m/s just before it strikes a 46-g golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 41 m/s. find the speed of the golf ball just after impact.
Question3
