A wooden block performs SHM on a frictionaless surface with frequency, `v_0`. The block carries a charge +Q on its surface. If now a uniform electric field `vecE` is switched-on as shown, then the SHM of the block will be

A

of the same frequecny and with shifted mean position

B

of the same frequency and with the same mean position

C

of changed frequency and with shifted mean position

D

of changed frequency and with the same mean postion .

Text Solution

Verified by Experts

The correct Answer is:
A
We should know that time peroid of spring block system is not affected by the application of constant force. Mean position of the block gets shifted due to constant force QE applied on it, but frequency remains same.

A wooden block performs SHM on a frictionless surface with frequency, v_(0) . The block carries a charge +Q on its surface. If now a uniform electric field vec (E) is switched on as shwon in figure., then the SHM of the block will be

A spring block system undergoes SHM on a smooth horizontal surface, the block is now given some charge and a uniform horizontal electric field E is switched on as shown in Fig. As a result

In the spring-block system shown, the block oscillates on a smooth horizontal surface with time period T. It is now given some charge Q and an electric filed E is swiched on, as shown. The block will not oscilalte with time period T', where

A block having mass 'm' ad carge q is resting on a fractionless plane at distance L from the wall as shown in fig.Discuss the motion of the block when a uniform electric field E is applied horizontally towards the wall assuming that collision of the block with the wall is perfectly elastic.

A 4.00 kg block carrying a charge Q = 50.0muC is connected to a spring for which k = 100 N/ m. The block lies on a frictionless horizontal track, and the system is immersed in a uniform electric field of magnitude E = 5.00 xx 10^5 V/m , directed as shown in figure. If the block is released from rest when the spring is unstretched (at x = 0). (a) By what maximum amount does the spring expand? (b) What is the equilibrium position of the block? (c) Show that the block's motion is simple harmonic and determine its period. (d) Repeat part (a) if the coefficient of kinetic friction between block and surface is 0.2.

A rectangular wooden block 5xxcm10cmxx10cm in size is kept on a horizontal surface with its face of largeest area on the surface. A minimum force of 1.5N applied parallel to the surface. Sets the block in sliding motion along the surface. If the block is now kept with its face of smaller area in contant with the surface, the minimum force applied parallel to the surface, to set the block in motion, is.

A 2.0-kg pistol fires a 1.0-g bullet with a muzzle speed of 1000 m/s. The bullet then strikes a 10-kg wooden block resting on a horizontal frictionless surface. The block and the embedded bullet then slide across the surface. What is the speed of the "bullet + block" system immediately after the bullet is embedded in the block?
