force system acting on particle can produce..options are...translation, rotational, deformation

Subhrajit Mukherjee 3rd May, 2021

Depending on the nature of the force system you can conclude the impact on the particle. So the answer can be all of the above.

I hope this answer helps. All the very best for your future endeavors!

derive an expression for the torque acting on the rectangular current carrying coil of a galvanometer

chandni deb 20th Apr, 2021

Dear Student,

F 1 = F 2 = BbI ,

As, these forces are equal and opposite, the net force is 0. Now, as theta component tends to 0, the perpendicular distance between the force of the coil also approaches 0. This makes the forces collinear and, the net force

For a system of particles under Central force field, the total angular momentum is conserved. Reason (R): The torque acting on such a system is zero.

Subhrajit Mukherjee 29th Mar, 2021

Under the central force field, the force acts along the line that joins the bodies so it has no rotary effect, that is, the torque is zero. Therefore, the angular momentum is conservative.

Both the assertion and reason are correct.

Dear Student,

This type of question is just simple theoretical concept based you should study from books and read them because you will be here find the solution but you will not able to  remember it.This assertion is true and you need to prove it.

Thanks

a force for=10N acting on a particle at an angle of 30 degrees with y-axis. find the horizontal and verticle components of force and then express force in terms of i and j

ginnisachdeva02_9364270 Student Expert 23rd Mar, 2021

Deepika,

The solution of the query asked is given below:

As the force is making 30 degree angle with the y-axis so , for the x-component of force: Sin of 30 degree * force

= 10N Sin(30) = 5 N

X-component is 5N

For Y-component : 10*cos(30) = 8.66N

So,

The torque of force F = 2i -3j +4k newton acting at the point r =3i +2k +3k metre about origin is (in N-m) a).6i-6j +12k b).17i - 6j -13k c).-6i +6k -12k d).-17i +6j +13k

ayanmukherjee045 17th Mar, 2021

Dear aspirant,

For this question you just simply need to apply the formula for torque which is r×F where r = (3-0)i +(2-0)j+(3-0)k and F=(2i-3j+4k) , just do the normal cross product calculations which will give you 17i -6j-13k. This is your final torque expression.

how can i selected in acting without giving offline audition but online audition? and where have to be send ?

Prachi Pant 18th Jan, 2021

Hi there,

The process of selection will depend upon your acting and drama skills. You can send your video samples at many production house after your deep research on the internet. You can only take part in any online audition where there are sponsored acting auditions (upcoming).

All the best.

hao can i give online acting audition ?

Prachi Pant 18th Jan, 2021

Hi there,

Majority of acting auditions that you see online are scams unless they have been sponsored by any director or producer. But amidst this pandemic, even the audition process has switched into online mode. In this case, you just need to find a genuine online website that offers you
