Previous Question: Two large vertical and parallelmetal plates having a separation of 1 cm are connected to a DC voltage source of potential difference X. Aproton is released at rest midway between the two plates. It is found to move at 45° to the vertical JUST after release. Then X is nearly Next Question: A small block is connected to one end of a massless spring of un-stretched length 4.9 m. The other end of the spring (see the figure) is fixed. The system lies on a horizontal frictionless surface. The block is stretched by 0.2 m and released from rest at t = 0. It then executes simple harmonicmotion with angular frequency rad/ s pie/3. Simultaneously at t = 0, a small pebble is projected with speed v from point P at an angle of 45º as shown in the figure. Point P is at a horizontal distance of 10 cm from O. If the pebble hits the block at t = 1s, the value of v is
