Question:

A wooden block performs SHM on a frictionless surface with frequency, v0. The block carries a charge +Q on its surface. If now a uniform electric field E is switched-on as shown, then the SHM of the block will be ?

of the same frequency and with the same mean position.

of changed frequency and with shifted mean position.

of changed frequency and with the same mean position.

of the same frequency and with shifted mean position.

An additional constant force will not change the frequency and will shift mean position.
